+# SYNOPSIS
+#
+# AX_PROG_CC_FOR_BUILD
+#
+# DESCRIPTION
+#
+# This macro searches for a C compiler that generates native executables,
+# that is a C compiler that surely is not a cross-compiler. This can be
+# useful if you have to generate source code at compile-time like for
+# example GCC does.
+#
+# The macro sets the CC_FOR_BUILD and CPP_FOR_BUILD macros to anything
+# needed to compile or link (CC_FOR_BUILD) and preprocess (CPP_FOR_BUILD).
+# The value of these variables can be overridden by the user by specifying
+# a compiler with an environment variable (like you do for standard CC).
+#
+# It also sets BUILD_EXEEXT and BUILD_OBJEXT to the executable and object
+# file extensions for the build platform, and GCC_FOR_BUILD to `yes' if
+# the compiler we found is GCC. All these variables but GCC_FOR_BUILD are
+# substituted in the Makefile.
