	* 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.

	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.
