Log: Clang hand-holding, mostly for issues caused by Clang defining GCC macros.
I do not think that removing the inclusion of "fenv.h" for clang is the right solution. According to http://llvm.org/bugs/show_bug.cgi?id=6907 it is a known compiler bug that clang fails to correctly load "fenv.h" in certain environments (several gcc versions installed...) I've been working around this by simply adding (see below)

And this actually removes fp-Support from Boost.Test.
Not good.
Please find a better solution. And/Or mark the relevant places with Todo containing a reference to the clang bug report.
