I'm using Mandrake 9.0 now, and plan to upgrade to 10.0.  Hopefully it
will have gcc >=3.3.2.  If you want I can release the current development
version of BabyChess 16, and you apply the changes there and send them to
the mailing list.

Do you think it is OK to have a flag like ./configure --no-gnome ?  I
could implement that for version 16.
