Yes. That is the case, only defined if including the pthread.h header or using the compiler -pthread flag. But I can see now why this would not be good for upstream.
Note:
See TracTickets
for help on using tickets.
That would break POSIX conforming platforms where:
#define _POSIX_THREADS 0
implies no threading support.
I take it that _POSIX_THREADS is either defined or not depending on whether threads are available?
