I chose to place it in suffix.hpp because I didn't think we wanted any order
dependencies between the compiler, standard library, and platform
configuration macros, which BOOST_HAS_CTYPE_MACRO_WORKAROUND would require.

I personally think it would be better to have checks that are specific to
compiler/platform/stdlib combinations in suffix.hpp than to put
compiler-specific checks in, i.e., the platform includes. However, my second
choice would be to put direct checks for GCC in bsd.hpp (and macos.hpp,
though I can't verify anything on that platform).
