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.
