Try this program.  It's what I use for testing...

  #include <pthread.h>
  #include <iostream.h>
  #include <X11/Xthreads.h>
  #include <X11/Intrinsic.h>

  int main(int argc, char *argv[]) {
    if(XInitThreads()) {
      cout << "Threads: supported level 1.\n";
      if(XtToolkitThreadInitialize()) {
        cout << "Threads: supported level 2.\n";
      } else {
        cout << "Threads: unsupported level 2.\n";
      }
    } else {
      cout << "Threads: unsupported level 1.\n";
    }
  }
