This patch looks good to me, but I'm unable to test it.
On what platform did you test it?
I retract the "looks good". These functions are also available
when compiling with `gcc -std=gnu89`, yet gnu89 does not
define __STDC_VERSION__.
This is the sort of issue I had in mind in my reply to this patch.
That's why autoconf (and other build systems) can figure out what
library functions are available and generate HAVE_CEILF, etc. macros for
them.
So, use
#if defined(__gnu_linux) || (your_new_c99_checks)
