    gmacros.h: Support deprecation macros better on clang-cl
    
    Use the GCC-style definition for the deprecation warning macros so that
    builds using those won't break due to how they are placed as clang-cl
    seems to not support __declspec(deprecated) very well.  Also make sure
    that we do indeed support the temparary disabling of deprecation
    warnings on clang-cl, as the MSVC ones don't really work on clang-cl.
