And the other way around. The main problem with Borland is that it only
supports one and a half platform on one processor.
If you want more than that, you'll have to use the (rather large) common
subset between FPC and Borland, and design modularly to accomodate for
changes. A bit of compromising. Not a Borland product with FPC compability
bolted on, and not the other way around.

Don't take it personally. It is meant as constructive criticism for the long
run. However if you are aware of the issues it is easier to work in the

That's what I'm talking about too. But a working version on most FPC targets.

Using a unit like dynlibs is the right way for that, you alraedy do that.
However with just win32 and Linux you are only halfway there. You have to
differentiate Linux into
1) Unix and linux
2) x86 specific and not.

How? How do I load FPC sockets unit, and avoid compiling in the non working
Linux kernel structuers in e.g. BSD?

I'd rather use the readily available one :-)
