Update.
2002-01-18 Wolfram Gloger <wg@malloc.de>
* malloc/malloc.c: Rewrite, adapted from Doug Lea's malloc-2.7.0.c.
* malloc/malloc.h: Likewise.
* malloc/arena.c: New file.
* malloc/hooks.c: New file.
* malloc/tst-mallocstate.c: New file.
* malloc/Makefile: Add new testcase tst-mallocstate.
Add arena.c and hooks.c to distribute. Fix commented CPPFLAGS.
2002-01-28 Ulrich Drepper <drepper@redhat.com>
* stdlib/msort.c: Remove last patch. The optimization violates the
same rule which qsort.c had problems with.
2002-01-27 Paul Eggert <eggert@twinsun.com>
* stdlib/qsort.c (_quicksort): Do not apply the comparison function
to a pivot element that lies outside the array to be sorted, as
ISO C99 requires that the comparison function be called only with
addresses of array elements [PR libc/2880].
