The function which implements this should be OS-dependent.  What you 
wrote might work for /bin/sh, but not for non-Posix systems such as 
MS-Windows.

To avoid ugly OS-specific #ifdef's, perhaps we should add a hook function 
pointer whcih a port could set to point to its private function.  Then 
the code you wrote could be the default.

This is controlled by the first character of the third argument to 
`getopt' and `getopt_long_only': if that first character is `-' or `+', 
`getopt' behaves differently as to the ordering of the options.  See the 
comments in getopt.c about the "enum ordering" type.
