Actually, the setjmp/longjmp thing was introduced only recently to simplify
the smooth rasterizer, and these instructions are ANSI.

There are basically two ways to do without them:

  a - get rid of them (use the old check-everything method)

  b - provide your own versions of setjmp/longjmp (these are generally
      compiler & platform-specific).

I'm rather reluctant to method a), could you see if you could find some
ST-specific implementation of setjmp/longjmp that you could provide in
your Pascal program. (since the instructions are only used _within_
FreeType, you wouldn't need to connect them to the Pascal ABI)..

Cheers,
