And who would use it? How would a UNIX program know that the "negative"
exit code represented a windows error code? A UNIX program would
interpret the low order bytes as indicating a signal number and would
think that there was a core dump if the appropriate bit was set. The
exitcode field is just for use by the cygwin DLL. There is no way for a
UNIX program to get more than eight bits (seven bits for signals) of
exit code from a process.
