 ./configure --disable-threads

will definitely work. Threads are not required for the 
operation of GTK+/GLib. The configure is supposed to fall
back properly if it doesn't find threads, but apparently 
on Slackware boxes it does something like finds
thread headers, but not thread libraries and dies
with an error message.

Well, sort of. Basically, if you want threading on Linux,
you want glibc. glibc integrates so much better with
LinuxThreads, that I wouldn't even consider trying to
use threads with libc5.

That being said, people did have some success using libc5
with LinuxThreads and even with older MIT (?) userland
pthreads. And (in theory) it should be possible to
get GLib and threads to work with one of these packages.

Generally, attaching configure output and config.log is
a good idea. (If you don't want to waste bandwidth
on the mailing list, mail it to gtk-bugs@gtk.org). In
this case, it really isn't necessary, since we have
other similar bug reports.
