On Linux 2.0.36 with WINE, it appears multi-tasking Ada programs
compiled with Gnat or ObjectAda do not run.  I understand this may be a
limitation of Linux "2.0.x and early 2.1.x".  If someone has a later
version, I would be very interested in hearing if multi-threading works,
and in particular, if the dining philosophers in diners.exe in exe.zip
at
ftp://members.aol.com/gmoran01/diners
(which was compiled with ObjectAda) run.  (A multi-tasking, but not
multi-threading, version does run on 2.0.36)
