Hmm.  Even the dinosaur called `emacs' moved to C99 a few years
ago :-) While being conservative, it doesn't make sense in case
everyone already moved on – I've looked into Wikipedia's C99 page, and
it seems that there aren't any major compilers that don't support it
(at least the very decent set of changes we would need or use).

I still vote for the possibility to change FT_UINT_TO_POINTER in a
configuration file, for example with some code in `ftstdlib.h'.

Indeed.
