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.
