Thanks, I hadn't noticed before, but you're right: Hugs suffers from the same bug. > My very vague memory from looking into this some years back was that DOS > programs don't have a consistently interpreted exit status the way Unix > programs do and use some kind of out-of-band communication to indicate > failure to the caller. Assuming this is the cause of the bug, shouldn't ghc's/hugs' implementation of System.system on Windows98 make use of this out-of-band communication (which would then seem to be the standard usage pattern on this platform), in order to provide a more useful exit status in our Haskell programs?
