1998-12-04  Zack Weinberg  <zack@rabi.phys.columbia.edu>

	* misc/sys/cdefs.h: Only include features.h if _FEATURES_H isn't
	defined.  gcc's redundant include optimizer isn't clever enough to
	prevent a reinclusion here.
	Define __restrict to the empty string only if not GCC or
	GCC version less than 2.92.

1998-12-03  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/configure.in: Fix last change.

1998-12-03  Mark Kettenis  <kettenis@phys.uva.nl>

	* time/strptime.c (strptime_internal): Make use of `%C' format
	specifier if it is seen together with the `%y' specifier.

1998-12-04  Ulrich Drepper  <drepper@cygnus.com>

	* po/sk.po: New file.

1998-12-03  Scott Bambrough  <scottb@corelcomputer.com>

	* sysdeps/arm/dl-machine.h (dl_start_user): Incorrect address
	for _dl_main_searchlist passed to _dl_init_next.

1998-12-02  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* math/libm-test.c: Expand literal tabs in strings.  Normalize
	whitespace.

1998-12-02  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/sys/fsuid.h: Fix spelling.
