I know this, but anyway here they are not precompiled and I don't like to
import all the Foundation in all .h

Not me. I prefer #import and I use it for all the ObjC headers !

Is there another way to check for OSX ?
Probably I'll put this in config.h since could be handled nicely by configure.

Ok, I'll take a look at it.

That's strange ! I've fixed all of these things some time ago since it does
not work with my gcc 2.95.

Not at the moment.

For PBX, not for PB. Anyway if there are no problems (Adam ??) I've no
problems to add them.

I saw your patch but as I already said I don't want to import all the
Foundation everywhere.
I'm currently updating all the header inclusion and hope to get working on
OSX (unfortunately I can't test it) and see where to put the compatibility
includes.
