	* sysdeps/unix/sysv/linux/getcwd.c: New file.  Use kernel information
	instead of longish search for the name.
	* sysdeps/posix/getcwd.c: Add support for use of the code as a
	backup solution.

1997-11-12 15:31  Philip Blundell  <pb@nexus.co.uk>

	* sysdeps/unix/sysv/linux/arm/sysdep.h (SYS_ify): Don't add
	SWI_BASE in twice.

1997-11-12 16:08  Ulrich Drepper  <drepper@cygnus.com>

	* intl/loadmsgcat.c [_LIBC] (fstat): Don't define as __fstat since
	now we have a definition as _fxstat.
	* libio/fileops.c: Likewise.
	* libio/oldfileops.c: Likewise.
	Reported by Andreas Jaeger <aj@arthur.rhein-neckar.de>.

	* sysdeps/wordsize-32/inttypes.h (SIG_ATOMIC_MAX): Correct value.
	* sysdeps/wordsize-64/inttypes.h (SIG_ATOMIC_MAX): Likewise.

1997-11-11  Paul Eggert  <eggert@twinsun.com>

	Add overflow checking for 64-bit time_t and 32-bit int.

	* time/time.h (__offtime): Now returns int.

	* time/offtime.c (__offtime): Return nonzero if successful;
	check for tm_year overflow.
	(DIV): New macro.
	(LEAPS_THRU_END_OF): Handle negative years correctly.

	* time/tzset.c (__tz_convert): Return NULL if offtime cannot convert.

	* time/mktime.c (ranged_convert): New function.
	(ydhms_tm_diff): Return nonzero if TP is null.
	(__mktime_internal): Handle cases correctly even if they are near or
	past the limits of time_t values that can be broken down to struct tm.
	(print_tm, check_result, main): Diagnose localtime failures.

	* manual/time.texi: Document the fact that localtime returns 0
	if the time can't be represented.

1997-11-12 06:03  Ulrich Drepper  <drepper@cygnus.com>

	* time/strftime.c (memset_space, memset_zero): Use MEMPCPY, not
	mempcpy.  Patch by Ken'ichi Handa  <handa@etl.go.jp>.

	* manual/time.texi: Document %F and %f format for strftime.

	* manual/arith.texi: Document copysign, nextafter and nan.

1997-11-06  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* test-installation.pl: New file. Tests for some installation
	problems.
