2003-12-01 Jes Sorensen <jes@wildopensource.com> * rt/tst-clock.c (do_test): Print message when skipping CLOCK_PROCESS_CPUTIME_ID test. * sysdeps/unix/sysv/linux/ia64/clock_getcpuclockid.c: New file. Provide CLOCK_PROCESS_CPUTIME_ID only if /proc/sal/itc_drift is 0. peek_token. This avoids some copying and reduces code size. (init_dfa): Initialize map_notascii. (build_wcs_upper_buffer): If map_notascii is zero use simplified
