+ GNUmakefile.
+ * Makefile: Similarly.
+
+2012-09-22 Daniel Richard. G <danielg at teragram dot com>
+
+ * GNUmakefile: Reordered the command lines in the "help" target
+ to match the ordering of the targets in the makefile, which IMO
+ is nicer to the eye; tweaked some of the parentheticals for better
+ clarity; delete *.manifest files, in case the user just finished
+ doing an MSVC build.
+ * Makefile: Use *.static_stamp for the static targets instead of
+ *.static; added a note re VC++6 and /EHs vs. /EHa; reordered the
+ targets, and added a number of new ones (e.g. VSE-small-static);
+ added a note recommending *-inlined and *-small-static to make
+ things a little easier for users bewildered by the large number of
+ targets; reworked the all-tests[-cflags] targets so that (1) more
+ useful targets are built first (the small-static targets make it
+ easier to track down compilation errors), (2) *-debug build and
+ test targets can be used, (3) less-useful build/test permutations
+ are enabled only if EXHAUSTIVE and/or MORE_EXHAUSTIVE is defined,
+ and (4) /MDd and /MTd are covered too; "nmake all-tests-cflags
+ EXHAUSTIVE=1 MORE_EXHAUSTIVE=1" takes a few hours to run; moved
+ some of the VCE targets up, since the pattern in the file was
+ already to list VCE targets first, then VSE, then VC; actually
+ touch the stamp file in the stamp targets.
+ * README.NONPORTABLE: It's "DllMain", not "dllMain".
+ * common.mk: Start of an attempt to define dependencies for
+ pthread.$(OBJEXT).
+ * implement.h: Generalized PTW32_BROKEN_ERRNO into
+ PTW32_USES_SEPARATE_CRT; don't do the autostatic-anchoring thing
+ if we're not building the library!
+ * pthread.h: Moved the PTW32_CDECL bit into sched.h. pthread.h
+ already #includes sched.h, so the latter is a good place to put
+ definitions that need to be shared in common; severely simplified
+ the errno declaration for Open Watcom, made it applicable only to
+ Open Watcom, and made the comment less ambiguous; updated the long
+ comment describing PTW32_BROK^WPTW32_USES_SEPARATE_CRT; added
+ (conditional) declaration of pthread_win32_set_terminate_np(), as
+ well as ptw32_terminate_handler (so that eh.h doesn't have to get
+ involved).
+ * pthread_cond_wait.c: Missed a couple of errno conversions.
+ * pthread_mutex_consistent.c: Visual Studio (either 2010 or 2008
+ Express, don't recall now) actually errored out due to charset
+ issues in this file, so I've replaced non-ASCII characters with
+ ASCII approximations.
+ * ptw32_threadStart.c: Big rewrite of ptw32_threadStart().
+ Everything passes with this, except for GCE (and I can't figure
+ out why).
+ * sched.h: Moved the PTW32_CDECL section here (and made it
+ idempotent); need to #include <stdlib.h> for size_t (one of the test
+ programs #includes sched.h as the very first thing); moved the
+ DWORD_PTR definition up, since it groups better with the pid_t
+ definition; also need ULONG_PTR, don't need PDWORD_PTR; can't use
+ PTW32_CONFIG_MSVC6, because if you only #include sched.h you
+ don't get that bit in pthread.h; use a cpp symbol
+ (PTW32_HAVE_DWORD_PTR) to inhibit defining *_PTR if needed. Note
+ that this isn't #defined inside the conditional, because there are
+ no other instances of these typedefs that need to be disabled, and
+ sched.h itself is already protected against multiple inclusion;
+ DWORD_PTR can't be size_t, because (on MSVC6) the former is "unsigned
+ long" and the latter is "unsigned int" and C++ doesn't see them as
+ interchangeable; minor edit to the comment... I don't like saying
+ "VC++" without the "Microsoft" qualifier; use PTW32_CDECL instead of
+ a literal __cdecl (this was why I moved the PTW32_CDECL bit into this
+ file).
+ * semaphore.h: Put in another idempotentized PTW32_CDECL bit here;
+ use PTW32_CDECL instead of __cdecl, and fixed indentation of function
+ formal parameters.
