Detailed Description

Include this file to disable GCC warning -Wcast-function-type introduced in GCC 8.1.

This diagnostic warns when a function pointer is cast to an incompatible function pointer. Existing APIs loading function pointer from library (like dlsym() or wglGetProcAddress()) have no possibility to return function of specified type nor to verify that exported symbol actually matches the expected function signature, so that unsafe function cast is unavoidable. There is no way to prevent this warning at OCCT level (until safer APIs is introduced), thus suppressing it is the only feasible way to avoid it. As this warning still can point out broken places, it should be suppressed only locally, where usage of function cast has been verified.
