I think I am missing something.

What is wrong with having one C90-compliant
source file in FPC (or my own derivative)
and then building it with hundreds of
different C compilers?

I am securing C first, so that's not a problem.
I personally will only be supporting Pascal on
a system that already has a working C90-compliant
C compiler. That's what I spent 27 years doing
on the x86 and S/3X0 (in tandem), to break
Microsoft's and IBM's respective monopolies.

BFN. Paul.
