Isn't this a case of "don't do that (CFLAGS), then" ?

If I update the gnulib patch per Paul's comment here:

  https://lists.nongnu.org/archive/html/bug-gnulib/2015-11/msg00006.html

then __STDC_CONSTANT_MACROS/__STDC_LIMIT_MACROS will be
unconditionally defined in config.h; I don't think defines
in config.h can be ifndefed.

Thanks,
