No, under Runtime you can only use _ONE_ threading facility. As long
as you have both pth_xxx and pthread_xxx API calls in your application
it will never work. So, first step is to replace either all Pthread
calls with Pth calls (simple, because Pth API is a superset of Pthread
API) or vice versa (usually possible for standard applications, but
might be tricky). Then, if you now have only Pth calls, use libpth from
Pth. Alternatively, if you then only have Pthread calls, use _EITHER_
libpthread from Pth or LinuxThreads.
