Depends-on:
configure.ac:
+dnl AC_PROG_CC_STDC should be added quite early to configure.ac.
+dnl Some compilers (e.g., AIX 5.3 cc) need to be in c99 mode
+dnl for the builtin va_copy to work. With Autoconf 2.60 or later,
+dnl AC_PROG_CC_STDC arranges for this. With older Autoconf AC_PROG_CC_STDC
+dnl shouldn't hurt, though installers are on their own to set c99 mode.
