incorrect exit status from cygwin exec to windows process

The process was exec'ed from a cygwin process, not a windows process...

For example, windows lanuched a cygwin process A. The cygwin process A
exec'ed another cygwin process B.  The exec'ed process should "replace" the
original cygwin process A, and process B's return value should be propagated
back to the windows process.
