+//! @file
+//! 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.
