I would like to differ. For me the best way seems to be to have the
extensions not automatically included. That will break existing
projects. (In most cases it will just cause warnings from the compiler
about methods not being defined) But it will also make clear that this
project will need to be adapted to be usable on OSX. For gui itself I am
willing to make the changes, in many cases just remove the use of the
extensions, in others just an additional include.
This is just what I think, it will be more important to get feedback
from the maintainers of GNUstep applications. If they think the clear
way is to much hassle for them, we should have the additions
automatically included.
