(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.

want to list them all here. The operations performed were all logical
transformations of the sources:
- trying to convert all enums and constants to CAPITALIZED_STYLE, with
#define definitions like
#define my_old_constants MY_NEW_CONSTANT
- big, big update of the documentation comments
* include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c,
include/freetype/ftimage.h: adding support for LCD-optimized rendering
though the new constants/enums:
FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V
FT_PIXEL_MODE_LCD, FT_PIXEL_MODE_LCD_V
this is still work in progress, don't expect everything to work correctly
though most of the features have been implemented.
* adding new FT_LOAD_XXX flags, used to specify both hinting and rendering
targets:
FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering
FT_LOAD_TARGET_MONO :: monochrome bitmaps
FT_LOAD_TARGET_LCD :: horizontal RGB/BGR decimated hinting & rendering
FT_LOAD_TARGET_LCD_V :: vertical RGB/BGR decimated hinting & rendering
note that FT_LOAD_TARGET_NORMAL is 0, which means that the default
behaviour of the font engine is _unchanged_.
changed the names of memory macros. Examples:
MEM_Set => FT_MEM_SET
MEM_Copy => FT_MEM_COPY
MEM_Move => FT_MEM_MOVE
ALLOC => FT_ALLOC
FREE => FT_FREE
REALLOC = >FT_REALLOC
FT_NEW was introduced to allocate a new object from a _typed_
pointer..
note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced
by FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer
arguments.
This results in _lots_ of sources being changed, but makes the
code more generic and less error-prone..
purposes..
* src/smooth/ftsmooth.c (ft_smooth_render): fixed a nasty hidden bug where
outline shifting wasn't correctly undone after bitmap rasterization. this
created problems with certain glyphs (like '"' of certain fonts..) and
the cache system..
`disable_horz_edges', `disable_vert_edges'.
* src/autohint/ahhint.c (ah_hint_edges_3, ah_hinter_hint_edges): Use
them (and remove static variables with the same names).

* docs/glnames.py: Updated to latest pstables.h changes.
* src/psnames/pstables.h: Add more `const'.
* src/pcf/pcfutil.c: Ditto.
* src/base/ftglyph.c (FT_Glyph_To_Bitmap): Fixing typo
(FT_Glyph_Done -> FT_Done_Glyph).
* include/freetype/ttnameid.h: Added some new Microsoft language
codes and LCIDs as found in Office Xp.

Hurd operating system as Unix-like. Fix submitted by Anthony Fok
<foka@debian.org>.
* src/type1/t1gload.c (T1_Load_Glyph): Set glyph control data to the
the Type 1 glyph charstring (used by conversion programs).
Submitted by Ha Shao <hashao@chinese.com>.
* src/base/ftgrays.c (grays_sweep): The function didn't exit
immediately if `num_cells' was 0 as it should. Thanks to Boris for
finding this out.
* src/base/ftglyph.c (FT_Glyph_To_Bitmap): Fixed memory leak when
bitmap rendering fails (thanks to Graham Asher).
* docs/docmaker.py, include/freetype/*.h: Updated the DocMaker
script to support chapters and section block ordering. Updated the
public header files accordingly.
* src/base/ftglyph.c (FT_Glyph_Copy): Advance width and glyph format
were not correctly copied.
- using FT_UNUSED instead of UNUSED
- using FT_LONG64 and FT_INT64 instead of LONG64 & INT64
- using FT_SIZEOF_INT & FT_SIZEOF_LONG instead of...
- removed the #ifdefs that used SIZEOF_INT, instead we now
use FT_Int32 and FT_UInt32 when needed to support
32-bits quantity correctly on 64-bits systems..
