The problem it will solve is that if someone has
already implemented a C compiler on a particular
system, FPC has a ready-made runtime library.

I just did it with PDOS/386. But that same code
will work on PDOS/3X0 and MVS 3.8J and z/OS too
as soon as the FPC targets that new environment.

Not true. It will work on AmigaOS too, another
place that PDPCLIB has been ported to.

I don't have to rewrite anything. It's all working
already. The effort (27 years) has already been done
to get the C side working. Adding Pascal (to the
same level as C90) is only a couple of days work,
as far as I can tell, and once the issues are known.

BFN. Paul.
