In stdbool.h, define bool, false, true only in gnu++98 GCC has meanwhile corrected that with the similar <https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=216679> "C++11 explicitly forbids macros for bool, true and false." Differential Revision: https://reviews.llvm.org/D40167 llvm-svn: 320135

Define _Bool, bool, true, and false macros in <stdbool.h> when we're in a GNU-compatible C++ dialect. Fixes <rdar://problem/8477819>. llvm-svn: 115028

Reinstate r173952, this time limiting it to exactly the form #define X X for which there is no point warning, ever. llvm-svn: 173991
