Oh, I was thinking memcpy() was standardized in C89 (so-called
ANSI C) and later standard C library has it. Do you mean you
want to use pre-C89 environment? FreeType2 is designed for
C89 and later, and I'm afraid that some available functions
(with same-name of C89 spec) works differently from C89 spec.
So you may get some errors that FreeType2 developers never
expected. Please post more detailed description on your environment.

I guess they are bugs, ft_memcpy() should be used.

If you disable anti-alias module, AAT/OpenType validator modules,
you can exclude most setjmp/longjmp, but I have no idea to disable
setjmp in src/sfnt/ttcmap.c.
