Yes, I suppose so, or a later patch release of Solaris 10.  Or some
other system that decides to ship a getopt.h with a getopt_long(),
getopt_clip(), and a GNU compatible getopt(), however unlikely that may
sound now.

Basically.  I was feeling guilty about not detecting the bug, but
detecting a feature of the system and assuming the bug.  This goes
against the whole Autoconf test design philosophy, I thought.  It's
almost as bad as using `uname -a |sed' to detect the version number and
using that to decide against the system getopt(), really.

The new test detects the actual bug.

What sort of bug are you worried about?
