Right.  Nothing subtle, then.  I guess FreeDCE needs some
work to run on NPTL or other POSIX-compliant threads packages,
as it's using Linuxthreads behavior that is an extension of POSIX threads.
(Surely FreeDCE doesn't *need* to longjmp out of a cancellation handler;
it can't be that hard to fix.)  Thanks for the heads up.
