Given that setjmp/longjmp are not thread safe, wouldn't it be better
to have FreeType2 drop them in the future ?
For the short term, makeing aliases for xf86setjmp/xf86longjump is
probably good enough. Even if the binary compat is broken, the need to
run a foreign OS font module is low, since they are open source.
The use of xf86setjmp/xf86longjmp should be discouraged.
