Update.
2001-08-07 Ulrich Drepper <drepper@redhat.com>
* sysdeps/ia64/memusage.h (GETTIME): Define using hp-timing.h
funcationality.
* sysdeps/ia64/hp-timing.h (HP_TIMING_NOW): Fix comment.
2001-08-07 Jakub Jelinek <jakub@redhat.com>
* malloc/memusage.c (initialized): New variable.
(init): If not yet initialized, call me().
(me): Do all dlsym calls here.
(malloc, realloc, calloc, free): If not yet initialized,
call me(). If in the middle of initializing, return NULL or
do nothing.
