Matthias pointed me at the man page for Solaris 10's getopt_long:
<http://docs.sun.com/app/docs/doc/816-5168/6mbb3hr99?l=en&a=view#indexterm-493>.

Based on that man page, I see two alternatives:

1. Always use getopt_long() in CVS since the Solaris 10 version supports
"+" as the start of the option string even though its getopt() does not.
2. Check for the getopt_clip() function, which should be unique to
Solaris, and use the GNULIB getopt.c when it is found.

I prefer door #2.  Trivial patch attached:

2005-05-05  Derek Price  <[email protected]>

    * m4/getopt.m4 (gl_GETOPT): Use GNULIB getopt on Solaris 10.

Matthias, would you mind verifying that this patch fixes CVS on your
Solaris 10?

Regards,

Derek
