Hi Robert,
Yes, testing the compiling of GNU/_np functions
is a better general solution.
Or another way is to use the C preprocessor instead.
In PThread.c++, instead test __USE_GNU:
< #if defined(HAVE_PTHREAD_SETAFFINITY_NP)
> #if defined(__USE_GNU)
pthread_setaffinity_np( pthread_self(), sizeof(cpumask), &cpumask);
Assuming pthread_setaffinity_np() is indeed a GNU-only extension
(your solution might be more universal).
