This is from the LinuxThreads README: http://pauillac.inria.fr/~xleroy/linuxthreads/README
"WARNING: Many existing libraries are not compatible with LinuxThreads, either because they are not inherently thread-safe, or because they have not been compiled with the -D_REENTRANT. For more info, see the FAQ.html file in this directory. A prime example of the latter is Xlib. If you link it with LinuxThreads, you'll probably get an "unknown 0 error" very early. This is just a consequence of the Xlib binaries using the global variable "errno" to fetch error codes, while LinuxThreads and the C library use the per-thread "errno" location. See the file README.Xfree3.3 for info on how to compile the Xfree 3.3 libraries to make them compatible with LinuxThreads." I dunno how to tell if something was compiled with this option...
