While C++11 was the first version of the standard to use C99 functionality, TR1 (for C++03) also does, and G++ does not distinguish between C++98 and C++03, or when TR1 is in use. Therefore, while not strictly correct for "pure" C++98, enabling C99 for all C++ usage is the simplest solution (and much better than always using -D_GNU_SOURCE as on Linux). See thread starting: https://sourceware.org/ml/newlib/2016/msg00297.html
This patch to newlib, along with the attached revised patches to GCC 5.3, allow _GLIBCXX_USE_C99 to be enabled for bare-metal targets.
