+To build this tool you first need to install Visaul C++ Studio .NET 2003,
+Visual Studio 2008 or Visual Studio 2010.
+
+Open the mhmake.sln, mhmakevc6.sln or mhmakevc10.sln file in Visual Studio
+depending on the version of Visual Studio and compile for Debug and for
+Release.
+2 executables are generated by this process:
+- Release\mhmake.exe : gnu make compatible make program with some specific
+  extension is make the build process faster.
+
+- Debug\mhmake_dbg.exe  : Has the same functionality but does extra
+  error checking on makefiles and has extra debugging options. This one
+  is advised to be used when creating makefiles. When the makefiles are
+  fully debugging mhmake.exe is a better choise because here the build
+  process will be faster. mhmake.exe is more likely to crash when badly
+  written makefiles are passed as input.
+
+To build with kdevelop4 on linux
+- run genkdev4.sh
+
+- run 'make' and 'make install' in the build and build.dbg directories
+
+or
+
+- open mhmake.kdev4 and build configuration build and build.dbg
+- run 'make install' in the build and build.dbg directories (as root)

+
+# In M4 1.4.x, every byte of $@ is rescanned.  This means that an
+# algorithm on n arguments that recurses with one less argument each
+# iteration will scan n * (n + 1) / 2 arguments, for O(n^2) time.  In
+# M4 1.6, this was fixed so that $@ is only scanned once, then
+# back-references are made to information stored about the scan.
+# Thus, n iterations need only scan n arguments, for O(n) time.
+# Additionally, in M4 1.4.x, recursive algorithms did not clean up
+# memory very well, requiring O(n^2) memory rather than O(n) for n
+# iterations.
+#
+# This file is designed to overcome the quadratic nature of $@
+# recursion by writing a variant of m4_foreach that uses m4_for rather
+# than $@ recursion to operate on the list.  This involves more macro
+# expansions, but avoids the need to rescan a quadratic number of
+# arguments, making these replacements very attractive for M4 1.4.x.
+# On the other hand, in any version of M4, expanding additional macros
+# costs additional time; therefore, in M4 1.6, where $@ recursion uses
+# fewer macros, these replacements actually pessimize performance.
+# Additionally, the use of $10 to mean the tenth argument violates
+# POSIX; although all versions of m4 1.4.x support this meaning, a
+# future m4 version may switch to take it as the first argument
+# concatenated with a literal 0, so the implementations in this file
+# are not future-proof.  Thus, this file is conditionally included as
+# part of m4_init(), only when it is detected that M4 probably has
+# quadratic behavior (ie. it lacks the macro __m4_version__).
+#
+# Please keep this file in sync with m4sugar.m4.
+
+# m4_foreach(VARIABLE, LIST, EXPRESSION)
+# --------------------------------------
+# Expand EXPRESSION assigning each value of the LIST to VARIABLE.
+# LIST should have the form `item_1, item_2, ..., item_n', i.e. the
+# whole list must *quoted*.  Quote members too if you don't want them
+# to be expanded.
+#
+# This version minimizes the number of times that $@ is evaluated by
+# using m4_for to generate a boilerplate into VARIABLE then passing $@
+# to that temporary macro.  Thus, the recursion is done in m4_for
+# without reparsing any user input, and is not quadratic.  For an idea
+# of how this works, note that m4_foreach(i,[1,2],[i]) defines i to be
+#   m4_define([$1],[$3])$2[]m4_define([$1],[$4])$2[]m4_popdef([i])

+# |     [m4_define([$1], _arg1$2)$3[]_foreach([$1], (m4_shift$2), [$3])])])

+# | m4_define(c, 3)
+# | foreach([f], [([a], [(b], [c)])], [echo f
+# | ])
+#
+# it gives
+#
+#  => echo 1
+#  => echo (2,3)
+#
+# which is not what is expected.
+#
+# Of course the problem is that many quotes are missing.  So you add
+# plenty of quotes at random places, until you reach the expected
+# result.  Alternatively, if you are a quoting wizard, you directly
+# reach the following implementation (but if you really did, then
+# apply to the maintenance of m4sugar!).
+#
+# | # foreach(VAR, (LIST), STMT)
+# | m4_define([foreach], [m4_pushdef([$1])_foreach($@)m4_popdef([$1])])
+# | m4_define([_arg1], [[$1]])

+# |    [m4_define([$1], [_arg1$2])$3[]_foreach([$1], [(m4_shift$2)], [$3])])])
+#
+# which this time answers
+#
+#  => echo a
+#  => echo (b
+#  => echo c)
+#
+# Bingo!
+#
+# Well, not quite.
+#
+# With a better look, you realize that the parens are more a pain than
+# a help: since anyway you need to quote properly the list, you end up
+# with always using an outermost pair of parens and an outermost pair
+# of quotes.  Rejecting the parens both eases the implementation, and
+# simplifies the use:
+#
+# | # foreach(VAR, (LIST), STMT)
+# | m4_define([foreach], [m4_pushdef([$1])_foreach($@)m4_popdef([$1])])
+# | m4_define([_arg1], [$1])

+# |  [m4_if($2, [], ,
+# |    [m4_define([$1], [_arg1($2)])$3[]_foreach([$1], [m4_shift($2)], [$3])])])
+#
+#
+# Now, just replace the `$2' with `m4_quote($2)' in the outer `m4_if'
+# to improve robustness, and you come up with a nice implementation
+# that doesn't require extra parentheses in the user's LIST.
+#
+# But wait -  now the algorithm is quadratic, because every recursion of
+# the algorithm keeps the entire LIST and merely adds another m4_shift to
+# the quoted text.  If the user has a lot of elements in LIST, you can
+# bring the system to its knees with the memory m4 then requires, or trip
+# the m4 --nesting-limit recursion factor.  The only way to avoid
+# quadratic growth is ensure m4_shift is expanded prior to the recursion.
+# Hence the design below.
+#
+# The M4 manual now includes a chapter devoted to this issue, with
+# the lessons learned from m4sugar.  And still, this design is only
+# optimal for M4 1.6; see foreach.m4 for yet more comments on why
+# M4 1.4.x uses yet another implementation.

+# whole list must *quoted*.  Quote members too if you don't want them
+# to be expanded.
+#

+## --------------------------------------------- ##
+## 10. Defining macros with bells and whistles.  ##
+## --------------------------------------------- ##
+
+# `m4_defun' is basically `m4_define' but it equips the macro with the
+# needed machinery for `m4_require'.  A macro must be m4_defun'd if
+# either it is m4_require'd, or it m4_require's.
+#
+# Two things deserve attention and are detailed below:
+#  1. Implementation of m4_require
+#  2. Keeping track of the expansion stack
+#
+# 1. Implementation of m4_require
+# ===============================
+#
+# Of course m4_defun AC_PROVIDE's the macro, so that a macro which has
+# been expanded is not expanded again when m4_require'd, but the
+# difficult part is the proper expansion of macros when they are
+# m4_require'd.
+#
+# The implementation is based on two ideas, (i) using diversions to
+# prepare the expansion of the macro and its dependencies (by Franc,ois
+# Pinard), and (ii) expand the most recently m4_require'd macros _after_
+# the previous macros (by Axel Thimm).
+#
+#
+# The first idea: why use diversions?
+# -----------------------------------
+#
+# When a macro requires another, the other macro is expanded in new
+# diversion, GROW.  When the outer macro is fully expanded, we first
+# undivert the most nested diversions (GROW - 1...), and finally
+# undivert GROW.  To understand why we need several diversions,
+# consider the following example:
+#
+# | m4_defun([TEST1], [Test...REQUIRE([TEST2])1])
+# | m4_defun([TEST2], [Test...REQUIRE([TEST3])2])
+# | m4_defun([TEST3], [Test...3])
+#
+# Because m4_require is not required to be first in the outer macros, we
+# must keep the expansions of the various levels of m4_require separated.
+# Right before executing the epilogue of TEST1, we have:
+#
+#          GROW - 2: Test...3
+#          GROW - 1: Test...2
+#          GROW:     Test...1
+#          BODY:
+#
+# Finally the epilogue of TEST1 undiverts GROW - 2, GROW - 1, and
+# GROW into the regular flow, BODY.
+#
+#          GROW - 2:
+#          GROW - 1:
+#          GROW:
+#          BODY:        Test...3; Test...2; Test...1
+#
+# (The semicolons are here for clarification, but of course are not
+# emitted.)  This is what Autoconf 2.0 (I think) to 2.13 (I'm sure)
+# implement.
+#
+#
+# The second idea: first required first out
+# -----------------------------------------
+#
+# The natural implementation of the idea above is buggy and produces
+# very surprising results in some situations.  Let's consider the
+# following example to explain the bug:
+#
+# | m4_defun([TEST1],  [REQUIRE([TEST2a])REQUIRE([TEST2b])])
+# | m4_defun([TEST2a], [])
+# | m4_defun([TEST2b], [REQUIRE([TEST3])])
+# | m4_defun([TEST3],  [REQUIRE([TEST2a])])
+# |
+# | AC_INIT
+# | TEST1
+#
+# The dependencies between the macros are:
+#
+#                3 --- 2b
+#               /        \              is m4_require'd by
+#              /          \       left -------------------- right
+#           2a ------------ 1
+#
+# If you strictly apply the rules given in the previous section you get:
+#
+#          GROW - 2: TEST3
+#          GROW - 1: TEST2a; TEST2b
+#          GROW:     TEST1
+#          BODY:
+#
+# (TEST2a, although required by TEST3 is not expanded in GROW - 3
+# because is has already been expanded before in GROW - 1, so it has
+# been AC_PROVIDE'd, so it is not expanded again) so when you undivert
+# the stack of diversions, you get:
+#
+#          GROW - 2:
+#          GROW - 1:
+#          GROW:
+#          BODY:        TEST3; TEST2a; TEST2b; TEST1
+#
+# i.e., TEST2a is expanded after TEST3 although the latter required the
+# former.
+#
+# Starting from 2.50, we use an implementation provided by Axel Thimm.
+# The idea is simple: the order in which macros are emitted must be the
+# same as the one in which macros are expanded.  (The bug above can
+# indeed be described as: a macro has been AC_PROVIDE'd before its
+# dependent, but it is emitted after: the lack of correlation between
+# emission and expansion order is guilty).
+#
+# How to do that?  You keep the stack of diversions to elaborate the
+# macros, but each time a macro is fully expanded, emit it immediately.
+#
+# In the example above, when TEST2a is expanded, but it's epilogue is
+# not run yet, you have:
+#
+#          GROW - 2:
+#          GROW - 1: TEST2a
+#          GROW:     Elaboration of TEST1
+#          BODY:
+#
+# The epilogue of TEST2a emits it immediately:
+#
+#          GROW - 2:
+#          GROW - 1:
+#          GROW:     Elaboration of TEST1
+#          BODY:     TEST2a
+#
+# TEST2b then requires TEST3, so right before the epilogue of TEST3, you
+# have:
+#
+#          GROW - 2: TEST3
+#          GROW - 1: Elaboration of TEST2b
+#          GROW:     Elaboration of TEST1
+#          BODY:      TEST2a
+#
+# The epilogue of TEST3 emits it:
+#
+#          GROW - 2:
+#          GROW - 1: Elaboration of TEST2b
+#          GROW:     Elaboration of TEST1
+#          BODY:     TEST2a; TEST3
+#
+# TEST2b is now completely expanded, and emitted:
+#
+#          GROW - 2:
+#          GROW - 1:
+#          GROW:     Elaboration of TEST1
+#          BODY:     TEST2a; TEST3; TEST2b
+#
+# and finally, TEST1 is finished and emitted:
+#
+#          GROW - 2:
+#          GROW - 1:
+#          GROW:
+#          BODY:     TEST2a; TEST3; TEST2b: TEST1
+#
+# The idea is simple, but the implementation is a bit evolved.  If you
+# are like me, you will want to see the actual functioning of this
+# implementation to be convinced.  The next section gives the full
+# details.
+#
+#
+# The Axel Thimm implementation at work
+# -------------------------------------
+#
+# We consider the macros above, and this configure.ac:
+#
+#           AC_INIT
+#           TEST1
+#
+# You should keep the definitions of _m4_defun_pro, _m4_defun_epi, and
+# m4_require at hand to follow the steps.
+#
+# This implements tries not to assume that the current diversion is
+# BODY, so as soon as a macro (m4_defun'd) is expanded, we first
+# record the current diversion under the name _m4_divert_dump (denoted
+# DUMP below for short).  This introduces an important difference with
+# the previous versions of Autoconf: you cannot use m4_require if you
+# are not inside an m4_defun'd macro, and especially, you cannot
+# m4_require directly from the top level.

+# 2. Keeping track of the expansion stack
+# =======================================
+#
+# When M4 expansion goes wrong it is often extremely hard to find the
+# path amongst macros that drove to the failure.  What is needed is
+# the stack of macro `calls'. One could imagine that GNU M4 would
+# maintain a stack of macro expansions, unfortunately it doesn't, so
+# we do it by hand.  This is of course extremely costly, but the help
+# this stack provides is worth it.  Nevertheless to limit the
+# performance penalty this is implemented only for m4_defun'd macros,
+# not for define'd macros.
+#
+# The scheme is simplistic: each time we enter an m4_defun'd macros,
+# we prepend its name in m4_expansion_stack, and when we exit the
+# macro, we remove it (thanks to pushdef/popdef).
+#
+# In addition, we want to detect circular m4_require dependencies.
+# Each time we expand a macro FOO we define _m4_expanding(FOO); and
+# m4_require(BAR) simply checks whether _m4_expanding(BAR) is defined.

+# by Autoconf but still possible by manipulation of the definition
+# tracked in macro NAME, include O(n) deletion of one element and O(n)
+# computation of set size.  Because the set is exposed to the user via
+# the definition of a single macro, we cannot cache any data about the
+# set without risking the cache being invalidated by the user
+# redefining NAME.

+# Can we do better?  Yes, because m4 gives us an O(1) search function
+# for free: ifdef.  Additionally, even m4 1.4.x gives us an O(1)
+# insert operation for free: pushdef.  But to use these, we must
+# represent the set via a group of macros; to keep the set consistent,
+# we must hide the set so that the user can only manipulate it through
+# accessor macros.  The contents of the set are maintained through two
+# access points; _m4_set([name]) is a pushdef stack of values in the
+# set, useful for O(n) traversal of the set contents; while the
+# existence of _m4_set([name],value) with no particular value is
+# useful for O(1) querying of set membership.  And since the user
+# cannot externally manipulate the set, we are free to add additional
+# caching macros for other performance improvements.  Deletion can be
+# O(1) per element rather than O(n), by reworking the definition of
+# _m4_set([name],value) to be 0 or 1 based on current membership, and
+# adding _m4_set_cleanup(name) to defer the O(n) cleanup of
+# _m4_set([name]) until we have another reason to do an O(n)
+# traversal.  The existence of _m4_set_cleanup(name) can then be used
+# elsewhere to determine if we must dereference _m4_set([name],value),
+# or assume that definition implies set membership.  Finally, size can
+# be tracked in an O(1) fashion with _m4_set_size(name).
+#
+# The quoting in _m4_set([name],value) is chosen so that there is no

+%# This file is processed in several stages.
+%# Here are the stages, as best as I can describe:
+%#
+%#   1. flex.skl is processed through GNU m4 during the
+%#      pre-compilation stage of flex. Only macros starting
+%#      with `m4preproc_' are processed, and quoting is normal.
+%#
+%#   2. The preprocessed skeleton is translated verbatim into a
+%#      C array, saved as "skel.c" and compiled into the flex binary.
+%#
+%#   3. At runtime, the skeleton is generated and filtered (again)
+%#      through m4. Macros beginning with `m4_' will be processed.
+%#      The quoting is "[[" and "]]" so we don't interfere with
+%#      user code.
+%#
+%# All generate macros for the m4 stage contain the text "m4" or "M4"
+%# in them. This is to distinguish them from CPP macros.
+%# The exception to this rule is YY_G, which is an m4 macro,
+%# but it needs to be remain short because it is used everywhere.
+%#
+/* A lexical scanner generated by flex */
+
+%#  Macros for preproc stage.
+
+%# Macros for runtime processing stage.

+%#
+%# Lines in this skeleton starting with a "%" character are "control lines"
+%# and affect the generation of the scanner. The possible control codes are
+%# listed and processed in misc.c.
+%#
+%#   %#  -  A comment. The current line is omitted from the generated scanner.
+%#   %if-c++-only  -  The following lines are printed for C++ scanners ONLY.
+%#   %if-c-only    -  The following lines are NOT printed for C++ scanners.
+%#   %if-c-or-c++  -  The following lines are printed in BOTH C and C++ scanners.
+%#   %if-reentrant     - Print for reentrant scanners.(push)

+%#   %if-bison-bridge  - Print for bison-bridge. (push)
+%#   %if-not-bison-bridge  - Print for non-bison-bridge. (push)
+%#   %endif        - pop from the previous if code.
+%#   %%  -  A stop-point, where code is inserted by flex.
+%#          Each stop-point is numbered here and also in the code generator.
