AC_PROG_CC_C99 should also be checking this. Probably we should error out if fails though.

I haven't been able to test this correctly errors on a non-C99 system.
If anyone has a system that has a supported version of autoconf and a compiler that doesn't support the for loop initialisation part of C99, please could you double-check it errors correctly?
