libstdc++ test case ext/headers.cc failed on arm-none-eabi

[Jonathan Wakely]

You'll have more luck asking the libstdc++ list so I've redirected this there.

There's not enough context to see what happened, the diagnostic is
crap, only showing the macro not where it's used.  The macro is not
used as a non-static data member initializers except in C++11 mode, so
I don't know how that could happen.
