I recently added the gcc-8 specific "-Wno-stringop-truncation" and "-Wno-restrict" options to BUILD_CFLAGS, both for "Darwin" (XCODE5 / clang, OSX) and otherwise (gcc, Linux / Cygwin). I also regression-tested the change with gcc-4.8 on Linux -- gcc-4.8 does not know either of the (gcc-8 specific) "-Wno-stringop-truncation" and "-Wno-restrict" options, yet the build completed fine (by GCC design). Regarding OSX, my expectation was that - XCODE5 / clang would either recognize these warnings options (because clang does recognize most -W options of gcc), - or, similarly to gcc, clang would simply ignore the "-Wno-xxx" flags that it didn't recognize. Neither is the case; the new flags have broken the BaseTools build on OSX. Revert them (for OSX only).
