> It was a common pattern to have "GCC diagnostic ignored" pragmas
> sprinkled over the code and only activate these pragmas for certain
> compilers (gcc and clang). Clang supports GCC's pragma for
> compatibility with existing source code, so #pragma GCC diagnostic
> and #pragma clang diagnostic are synonyms for Clang
> (https://clang.llvm.org/docs/UsersManual.html).

> Now that effort is being made to make the code compatible with MSVC
> these expressions would become more complex. It makes sense to hide
> this complexity behind macros. This makes maintenance easier as these
> macros are defined in a single place. As a plus the code becomes
> more readable as well.
