This is now fixed, however the _Generic() usage that we had there is also present in tgmath.h, and so this file will also need to be fixed in the same way. I've now tested the macros with clang/c99, clang/c11, clang/c++98 and clang/c++11, and gcc/c89 and they all seem to work for unqualified, const, volatile, and const-volatile qualified types. I've added Ed to the cc: list, as he wrote this code in tgmath.h.
