To my best of my knowledge I think this problem occurs
because Slackware (and possibly some other libc5-based
distribution) shipped with a pthread.h but without
a real functioning POSIX threads distribution.

configure should be a bit smarter, and once it realizes
that you don't have a functioning thread library,
just go ahead, pretend it didn't see the pthread.h
and continue without threads.

You can safely follow the above instructions and
run configure --disable-threads. Few GTK+ programs
require threading support, and they wouldn't run
on your system anyways.
