Thread Safe Xlibs

["Spud" <spud has a godcomplex com>]

    I run Slackware v3.6, which uses libc5. I haven't run into many
problems, since I've installed
linuxthreads and thread safe Xlibs. I know this isn't GNOME specific, but i
would appreciate any
answers. While looking over Brian Masney's www site (gFTP), I saw he had
thread safe Xlibs available
for download. Although I have some on my system already, I am curious as how
to produce them for my own system?
