What is the difference between AC_PROG_CC_STDC and AC_PROG_CC_C99? As I understand it, AC_PROG_CC_STDC is a "moving target", whereas AC_PROG_CC_C99 is not. Since the requirements of a gnulib module should not vary depending on the version of autoconf in use, I think AC_PROG_CC_C99 should then be preferred over AC_PROG_CC_STDC. Right? Also, the AC_REQUIRE that you mention ought to happen early. Maybe it is sufficient to put it in the configure.ac-early section of the module, maybe not.
