What is pthread priority support?

Your question on the forum (always a good idea to put all the relevant details 
in the email) was about whether some code under the following #ifdef got 

#if defined(Q_OS_DARWIN) || !defined(Q_OS_OPENBSD) && 

Well, I think you have all of the information at your fingertips. On Linux, 
neither Q_OS_DARWIN nor Q_OS_OPENBSD will be defined. The other constant comes 
from glibc (unistd.h in particular). Check whether it defines the macro to a 
value greater than or equal to 1.
