FYI I'm using autoconf 2.67.
Here's why I need to insert macros into AC_PROG_CC:
I have some users who refuse to use anything but Intel's icc and ifort, version 8.1. But, they have a newer
GCC installed (4.1.2) which causes icc to barf with "invalid GNU version number: 412" (causing
configure to report "C compiler cannot create executables"). The problem can be worked-around if
they add CFLAGS="-gcc-version-340". But these users want me to add this flag conditionally during
configure. But how?
Your configure file should NOT have to do this. If the user has a
compiler that needs a particular CFLAGS set, then they should pass that
particular CFLAGS as an argument to configure, or use the config.site
mechanism to automatically set up their environment with proper CFLAGS.
