thread implementation

[Scott Moser <smoser saintjoe edu>]

Hi,
	I'm working on a freshly installed slackware-3.5 machine, and
trying to build gtk-1.2.  It errors, telling me that it can't find the
'libraries for the thread implementation posix'.  I guess I could compile
it without thread support, but don't want to if I don't have to.

Any Help?
the errors are below.
Thanks in advance,
Scott Moser

                provide information on your thread implementation.
                You can also run 'configure --disable-threads' 
                to compile without thread support.
