(CFLAGS), builds/compiler/gcc.mk (CFLAGS): Remove -fno-strict-aliasing. Say you have `(Foo*)x' and want to assign, pass, or return it as `(Bar*)'. If you simply say `x' or `(Bar*)x', then the C compiler would warn you that type casting incompatible pointer types breaks strict-aliasing. The solution is to cast to `(void*)' instead which is the generic pointer type, so the compiler knows that it should make no strict-aliasing assumption on `x'. But the problem with `(void*)x' is that seems like in C++, unlike C, `void*' is not a generic pointer type and assigning `void*' to `Bar*' without a cast causes an error. The solution is to cast to `Bar*' too, with `(Bar*)(void*)x' as the result -- this is what the patch does. * include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP), include/freetype/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Remove cast on lvalue, use a temporary pointer instead. Cast temporarily to (void*) to not break strict aliasing. * include/freetype/internal/ftmemory.h (FT_MEM_ALLOC, FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC, FT_MEM_FREE), src/base/ftglyph.c (FT_Glyph_To_Bitmap): Cast temporarily to (void*) to not break strict aliasing. * src/base/ftinit.c (FT_USE_MODULE): Fix wrong type information. * builds/unix/configure.ac (XX_CFLAGS): Remove -fno-strict-aliasing. * src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c -- it is currently loaded from ttsbit.c. Other formatting.
