	* libio/filedoalloc.c (_IO_file_doallocate): A few more minor
	cleanups and improvements.

2001-07-18  Andreas Schwab  <schwab@suse.de>

	* posix/regex.c (WORDCHAR_P) [WCHAR]: Also return true for the
	underscore character.

2001-07-18  Jakub Jelinek  <jakub@redhat.com>

	* malloc/malloc (new_heap): Don't call munmap for zero length.

2001-07-18  Ulrich Drepper  <drepper@redhat.com>

	* libio/filedoalloc.c (_IO_file_doallocate): Use DEV_TTY_P if
	available to determine whether descriptor is for tty before
	calling isatty.

	* sysdeps/unix/sysv/linux/device-nrs.h: Define DEV_TTY_P.
	* sysdeps/generic/device-nrs.h: Likewise.
