* sysdeps/ia64/fpu/libm_error.c (__libm_error_support): Don't abort.
2005-08-17 Robert Love <rml@novell.com> * sysdeps/unix/sysv/linux/sys/inotify.h: Add IN_MOVE_SELF event. 2005-08-19 Bruno Haible <bruno@clisp.org> * intl/localealias.c (read_alias_file): In case of failure, close the file descriptor and sort the array before returning. 2005-08-19 Ulrich Drepper <drepper@redhat.com> * malloc/Makefile: Link libmemusage.so with ld.so. * malloc/memusage.c: Use atomic operations for all counter and size computations. Handle thread stacks. * sysdeps/generic/memusage.h: Define memusage_cntr_t and memusage_size_t. * sysdeps/i386/i686/memusage.h: New file. * include/atomic.h: Define atomic_max and atomic_min. * debug/tst-chk1.c: Add tests for mbstowcs and wcstombs.
