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)
