    MSVC Builds: Drop GCC Requirement
    
    As we are running the preprocessor without using stdin as its input, we can
    now drop the MSVC build-time dependency on a MinGW/GCC installation for
    introspection files, which means we also don't need to supply definitions
    for time_t anymore.
