Subject: Compat glue needed for Solaris 9 and 10.

Thanks to Sevan Janiyan <venture37 at geeklan dot co dot uk> for
reporting the Solaris 10 issues, to Jan Holzhueter <jh at opencsw
dot org> for some additional insight, and to OpenCSW in general for
providing me with a Solaris 9/10/11 testing environment.
