Re: 7.4.2 on Solaris 9 - Error

Changing config.status, now that's what I call a quick and dirty hack.

The attached diff against 7.4.2 incorporates Joe Conway's checks for
getqwuid_r() has 4/5 arguments with a pthread compile autoconf check
that I found a while back in the gnu autoconf archives.

I think we should change alltogether to that pthread check.
