* elf/rtld.c: Add a few __builtin_expects where they will improve
	a lot.

1998-11-05  Ulrich Drepper  <drepper@cygnus.com>

1998-11-04  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* libio/genops.c (_IO_least_marker): Add additional parameter
	end_p replacing fp->_IO_read_end.
	(save_for_backup): Likewise.  All callers changed.  Use _IO_size_t
	and _IO_ssize_t instead of int.
	(_IO_switch_to_main_get_area): Remove use of _IO_save_ptr.
	(_IO_switch_to_backup_area): Likewise.  Fix comments.
	(_IO_seekmark): Undo last change.
	(_IO_default_pbackfail): Correct use of backup area.
	* libio/libio.h (_IO_FILE_complete): Remove _IO_save_ptr.

Because of the United States export restriction on DES implementations,
we are distributing this code separately from the rest of the C
library. There is an extra distribution tar file just for crypt; it is
called `glibc-crypt-2.0.99.tar.gz'. You can just unpack the crypt
called `glibc-crypt-2.0.100.tar.gz'. You can just unpack the crypt
distribution along with the rest of the C library and build; you can
also build the library without getting crypt. Users outside the USA
can get the crypt distribution via anonymous FTP from ftp.ifi.uio.no
