ISO C99 is not the C++ spec, and C++11 specifically states that
__STDC_LIMIT_MACROS is not required.  You are probably running into
fallout from our recent patches to make things available on C++
regardless of whether glibc followed the C++11 recommendations:

Are you sure you are using the latest gnulib sources, and that your
program included <config.h> first?  Can you provide the actual test case
you used to provoke the compilation failure?
