    Add MSVC implementations of G_GNUC_*_IGNORE_DEPRECATIONS
    
    As Visual Studio 2008 and later have support for the __pragma keyword,
    where the compiler pragmas can be used in a macro, we can support
    G_GNUC_BEGIN_IGNORE_DEPRECATIONS and G_GNUC_END_IGNORE_DEPRECATIONS
    for Visual Studio 2008 and later, so many deprecation (C4996) warnings
    can be suppressed when using these compilers when we use these macros
    in the code.
