Ok, I'll give it a try.  If all else fails, I could fall back to the
current patch everywhere.  Unfortunately, splitting on version number
doesn't really help, because older versions of OpenSolaris
(i.e. *-*-solaris2.11) have the bug, while newer ones are fixed.  That's
why it seems more appropriate to perform a feature test.

Thanks, I'll check it in there ASAP.
