Update.
2000-01-19 Ulrich Drepper <drepper@cygnus.com> * locale/weight.h (findidx): Little optimization. Correctly return offset in indirect table. * locale/programs/ld-collate.c (struct element_t): Add mblast and compute it where necessary. (insert_weights): Correctly handle missing weights in ellipsis expression. (handle_ellipsis): Correctly enqueue new element. (collate_output): Insert indirect references in the right order.
