Update. 

1998-03-06 11:35  Ulrich Drepper  <drepper@cygnus.com>

	* posix/wordexp-test.c: Change testsuite so that it can run even
	for ~root != /root.

1998-03-06  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* math/libm-test.c (catanh_test): Change epsilon for gcc 2.8.1.

1998-03-05  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/i386/sysdep.h (SYSCALL_ERROR_HANDLER):
	Don't store into global errno if we already store through
	__errno_location.
	* sysdeps/unix/i386/sysdep.S: Likewise.
	* sysdeps/unix/alpha/sysdep.S: Likewise.
	* sysdeps/unix/sysv/linux/sparc/sparc64/brk.S: Likewise.
	* sysdeps/unix/sysv/linux/sparc/sparc64/clone.S: Likewise.
	* sysdeps/unix/sysv/linux/sparc/sparc64/sysdep.h: Likewise.  Add
	missing return to SYSCALL_ERROR_HANDLER for (!_LIBC_REENTRANT &&
	PIC).

1998-03-05  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/generic/sysdep.h (L): Remove definition.
	* sysdeps/i386/sysdep.h (L): Define it here instead.

1998-03-05  Thorsten Kukuk  <kukuk@vt.uni-paderborn.de>
	* nss/getXXbyYY_r.c: Check __nss_not_use_nscd_* variable for
	running nscd.
	* nscd/nscd_getgr_r.c: Set __nss_not_use_nscd_group variable.
