I think you can effectively already do it. Like this:

  gl_LOCK
  if test $gl_threads_api = pth; then
    AC_FATAL([The pth threads implementation is not supported by this package.])
  fi

You are welcome to contribute a module for this.

Likewise. You find some code for this purpose at the top of tests/test-lock.c,
which you may be able to reuse.

Enhancement request to Ralf Engelschall? :-)
