(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.

drastically reduce the heap usage of FreeType, especially in the case
of memory-mapped files. The idea is to avoid loading and decoding tables
in the heap, and instead access the raw data whenever possible (i.e.
when it doesn't compromise performance).
This had several impacts: first, opening vera.ttf uses a ridiculous amount
of memory (when the FT_Library footprint is accounted for), until you start
loading glyphs. Even then, you'll save at least 20 Kb compared to the non
optimized case. performance of various operations, including open/close
has also been dramatically improved.
More optimisations to come. The auto-hinter eats memory like crazy? This
must be stopped...
src/truetype/ttpload.c, src/truetype/ttpload.h, src/truetype/ttgload.c:

optimizations used to reduce the heap footprint of memory-mapped TrueType
files.
* src/truetype/ttpload.c (tt_face_load_loca, tt_face_get_location,

into the heap.
* src/truetype/ttpload.c: only load the CVT and fpgm tables when the
bytecode interpreter is compiled in.
in the memory debugger. Also a new function FT_DumpMemory() was added.
It is only available in builds with FT_DEBUG_MEMORY defined, and you
must declare it in your own code to use it, i.e. with something
like:
extern void FT_DumpMemory( FT_Memory );
...
FT_DumpMemory( memory );
