The shield library offers warning suppresion of C/C++ header files.

It suppresses warnings for clang, GCC and MSVC compilers. This is particularly useful when third party libraries' warnings (relating to the library itself) create compilation noise and/or compilation to fail (e.g. when treating warnings as errors on a project).

The suppression works by wrapping included headers with a shield ON and OFF like in the example below.

Warning: Omitting the OFF header might result in undesired suppression of warnings (for example with unity builds).

Example:

#include <shield/on.h>

#include <concurrentqueue.h>

#include <shield/off.h>

A similar library that has the same purpose is leathers. The reason that we went with a new library for suppressing warnings is the fact that we didn't want to have to drag boost along as the compiler can also be determined without it.

The list of warnings suppressed might not be complete. Please file an issue if you found a warning that should be added to the list.
