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.
