* sysdeps/posix/sysconf.c (__sysconf): Use #if _POSIX_FOO > 0
rather than #ifdef _POSIX_FOO for options. We should return -1 at runtime for an option defined to 0 at compile time. * sysdeps/mach/hurd/bits/posix_opt.h: Define many missing options, many to -1 or 0. 2006-03-05 Roland McGrath <roland@redhat.com> * sysdeps/unix/sysv/linux/sysconf.c (__sysconf) [__NR_clock_getres || HP_TIMING_AVAIL]: Handle _SC_CPUTIME, _SC_THREAD_CPUTIME.
