  * builds/amiga/makefile.os4 (WARNINGS), builds/compiler/gcc-dev.mk
  (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.
