To translate the above: I have changed the cygwin_internal function so
that when the function is given an argument that it doesn't understand
it will set errno to ENOSYS and return -1.  This is likely to happen
when a program is built with a newer version of cygwin but is trying to
retrieve information from an older DLL.
