This is much better as prefixed double underscores are reserved for the implementation when it comes to identifiers. Another reason its better, is that, on Windows, where __forceinline is a compiler built-in, with the previous define, header inclusion software that detects unnecessary includes will erroneously flag usages of Compiler.h as unnecessary (despite being necessary on other platforms). So we define a macro that's used by Windows and other platforms to ensure this doesn't happen.
