 773 dnl It sets the PTHREAD_LIBS output variable to the threads library and

 778 dnl
 779 dnl Also sets PTHREAD_CC to any special C compiler that is needed for

 781 dnl (This is necessary on AIX to use the special cc_r compiler alias.)
 782 dnl
 783 dnl NOTE: You are assumed to not only compile your program with these
 784 dnl flags, but also link it with them as well. e.g. you should link
