 From your words I guess that <pthread.h> and <ntpl/pthread.h> are 
incompatible and you can only include one of them (maybe each one refer 
to a different pthread implementation)?

If so, you could just add the "/usr/include/nptl/" to the front of your 
include directories (-I option in gcc) so that

#include <pthread.h>

includes ntpl/pthread.h instead of pthread.h. That supposing 
ntpl/pthread.h has all the needed pthread declarations (since NTPL is an 
implementation of pthread, I suppose that should be true) used by 
Interprocess. Or am I missing something?
