I think it's technically not true that they violate POSIX namespace
requirements, since they're only defined in the non-conforming modes.

The reason I originally proposed the change is that libstdc++
force-enables _GNU_SOURCE, which means people writing in C++ _can't_
avoid these nonstandard macros by using a strict conformance mode.
