[PATCH] Add SSE math and C++ namespace support to i386 bits/mathinline.h

[Roland McGrath]

This looks OK to me.  Unfortunately, the real testing that's needed is with
compilers < 3.4.  If you can do that it would increase confidence in the
change.  But either way, I think it's worthwhile enough to be able to
complete the header unification that this should go in before 2.16.

Thanks,
Roland
