Perhaps this snippet from the autoconf documentation is helpful:

 - Macro: AC_PROG_CC ([COMPILER-SEARCH-LIST])
   Determine a C compiler to use.  If `CC' is not already set in the
   environment, check for `gcc' and `cc', then for other C compilers.
   Set output variable `CC' to the name of the compiler found.
   ...
   If using the GNU C compiler, set shell variable `GCC' to `yes'.

Thus configure.ac could add the gcc specific options to CFLAGS if GCC is
set in this way.

Greetings
