Doesn't fpc support ifdef? I can see your point, except if all you support are 
system calls, you will need to support each different system's calls. If you 
support a libraries interface then that interface doesn't change for the 
major functions. (strcpy hasn't changed for years!) As a matter of fact one 
of the libraries jobs is to hide the differences between the different 
operating systems.

I can't think of an immediate use, but I'm sure it will come in handy.
