GLibC_STD_VERSION

The C standard version the code is compiling against, it’s normally defined with the same value of __STDC_VERSION__ for C standard compatible compilers, while it uses the lowest standard version in pure MSVC, given that in such compiler the definition depends on a compilation flag.

This is granted to be undefined when compiling with a C++ compiler.
