Hi! Even if you run say i486 or i586 glibc on i686, HP_TIMING_AVAIL is not defined and therefore sysconf (_SC_{,THREAD_}CPUTIME) should IMHO return -1 in that case. For i686 compiled glibc, it has no sense to test for i386 or i486 CPU. 2004-10-05 Jakub Jelinek <jakub@redhat.com> * sysdeps/unix/sysv/linux/i386/sysconf.c: Include hp-timing.h.
