Well, it turns out that if getopt_long is not in the system's libc,
then postgres uses the getopt_long that is packaged with it.  This
version works like I think it should -- it expects the non-option
argument at the end.

The getopt_long on Mac and I guess also Linux have been made non-
Posix compliant.  They accept options after the non-option argument.
What is really disturbing is they alter argv.  I find that somewhat a
bad idea but, I guess no one really cares about consistency or
traditions.

Anyhow... that is the reason AIX does it the way I expect it but the
others do not.
