Okay, we've upgraded to Linux 2.0 with gcc 2.7.2. We can use either ELF or a.out, (although we prefer ELF.) Which version would be best for this configuration? [At one time we had one problem with GPC lookng for "crt0.o". Our configuration doesn't even have this file, but perhaps (as Peter suggested) we had the wrong compiler version.] -john jm_black@csunix1.lvc.edu
