	by Stephen R. van den Berg.

	* sysdeps/generic/_strerror.c: _strerror_internal now takes
	three argument and has and explicit buffer length.
	* sysdeps/mach/_strerror.c: Change for new interface with three
	arguments.
	* stdio/perror.c, stdio/vfprintf.c: Callers changed.

	* sysdeps/posix/utimes.c: Include <utime.h> for prototype.
	(utimes): First parameter to utime must be file, not path.

	* sysdeps/posix/sysconf.c (__sysconf): Test for CLK_TCK in case
	_SC_CLK_TCK and return it when available.
	Test for STREAM_MAX in case _SC_STREAM_MAX and return it when
	available.
	Add case for _SC_2_LOCALEDEF which is now available.
