Well, as someone experienced in running ACATS tests (but not with GNAT), the
list of tests suggests that there really are bugs here. The first two you
listed are tasking tests that might have timing errors (and thus there might
not be a real problem), but the rest are I/O tests and tests of the contents
of System. I can't think off-hand of how they could fail unless there is a
bug somewhere.
