1997-06-04 20:57  Ulrich Drepper  <drepper@cygnus.com>

	* manual/string.texi: Add comments to discourage use of index and
	rindex.
	(strtok, strsep): Apply function on copy of the strings in example.
	(l64a): Add example.

	* posix/unistd.h: Correct value for _POSIX_VERSION.

	* sunrpc/Makefile (defines): Remove definition.

	* sysdeps/ieee754/nan.h: Correct typo.

1997-06-04 10:50  Fila Kolodny  <fila@ibi.com>

	* posix/unistd.h: Add definition of __fchdir corresponding to fchdir.

	* login/utmp_daemon.c: Correct location of utmpd.h.

1997-06-03 19:16  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* Makerules: Rename $(common-objpfx)distinfo-$(subdir) to
	$(objpfx)distinfo.
	* rpm/Makefile (distinfo): Adapted.

1997-06-03 18:32  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* rpm/Makefile (install-slib): Collect shared libraries here
	instead of in install-lib, including libc.
	(instvars): Add slib.

1997-06-03 18:23  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* login/Makefile (libutil-routines): Add updwtmp.

1997-06-03 16:16  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* monetary.h: New file, needed for localedata/tst-fmon.c.

1997-06-02 20:31  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* math/libm-test.c (cpow_test): Add epsilon for long double in
	test for 2^10.
	(identities): Add epsilon for float in second identity test.

	* sysdeps/m68k/huge_val.h: Change GCC's HUGE_VAL{,F,L} to use
	DI and SI mode integers instead of bytes.  Fix value of HUGE_VALL.

	* sysdeps/m68k/nan.h: New file.

	* sysdeps/m68k/fpu/__math.h (isgreater, isgreaterequal, isless,
	islessequal, islessgreater, isunordered): Fix assembler syntax.

	* sysdeps/m68k/fpu/fraiseexcpt.c: Do it right so that gcc doesn't
	optimize out the operations.

	* sysdeps/libm-ieee754/s_nan.c: Use NaN macro instead of static
	constant.
	* sysdeps/libm-ieee754/s_nanf.c: Likewise.
	* sysdeps/libm-ieee754/s_nanl.c: Likewise.

	* math/carg.c [NO_LONG_DOUBLE]: Add alias for long double
	function.
	* sysdeps/libm-ieee754/s_erf.c: Likewise.
	* sysdeps/libm-ieee754/s_fdim.c: Likewise.
	* sysdeps/libm-ieee754/s_fmax.c: Likewise.
