gmacros.h: Use static_assert on MSVC if possible

Browse Source 
Visual Studio 2010 and later support static_assert on both C and C++,
but we can only enable it for plain-C code on Visual Studio 2013 and
later, as apparently the static_assert macro implementation will carry
out something after defining certain variables.

For C++ code, we use static_assert on Visual Studio 2010 and later.
