The basic purpose of every GNU package is to add to what the GNU
system can do.  Making a GNU program run on some other system is not a
central goal, but we encourage people to implement that if they wish.

It would be beneficial to make GCC support MacOS if it would lead
to more adoption of GCC.  Otherwise, we don't especially care.

If extensions to Objective C make that language better, it would be
good to implement them.  GNUtep doesn't use them now, but maybe it
would use them if they were available.
