--- Comment #2 from Ramana Radhakrishnan <ramana at gcc dot gnu.org> ---
This is not just the atomicity tests that are affected.
Now that we've switched to C++ in the main compiler, folks (especially in the
business of building cross-compilers) just set CXXFLAGS in the environment and
assume that this implies that the compiler built is built with the appropriate
CXXFLAGS. So, it's very easy to build a libstdc++ with the value of CXXFLAGS
set to something that wasn't expected. The build system appears to honour the
difference between CFLAGS and CFLAGS_FOR_TARGET, so it is natural that folks
expect that CXXFLAGS to behave in the same fashion.
