configure fails detection for ICC compilers, because giving an .m file does not
produce an error (this might also be true for the microsoft compiler also
failing on FATE, I can't check):

I still don't have a better idea how to handle it generically, though.
Checking with "check_header" at least only fails on Mac OS X >= 10.7 running
GCC, IIRC.
