Ensure C99 and C11 interfaces are available for C++ [BZ #21326]
This patch ensures that the C99 and C11 features required by C++ are defined according to the value of the __cplusplus macro, and not just because G++ always defines _GNU_SOURCE. This will allow G++ to stop defining _GNU_SOURCE some day, without causing the C99 and C11 interfaces to disappear for C++ programs. [BZ #21326] * include/features.h [__cplusplus >= 201103] (__USE_ISOC99): Define. [__cplusplus >= 201703] (__USE_ISOCXX17, __USE_ISOC11): Define. * math/Makefile (test-math-cxx11): New test. * math/test-math-cxx11.cc: New file.
