Update.

1999-06-23  Zack Weinberg  <zack@rabi.columbia.edu>

	* libio/stdio.h: Define stdin, stdout, stderr as macros.
	* math/complex.h: Don't define
	CX_LIMITED_RANGE_{ON,OFF,DEFAULT}.  These are *pragmas* not
	macros.
	* wcsmbs/wchar.h: Fix comment.

	* grp/grp.h: Use __foo_t_defined convention to typedef things
	only once.
	* io/sys/stat.h: Likewise.
	* libio/stdio.h: Likewise.
	* posix/unistd.h: Likewise.
	* posix/sys/types.h: Likewise.
	* posix/sys/wait.h: Likewise.
	* pwd/pwd.h: Likewise.
	* signal/signal.h: Likewise.
	* sysdeps/generic/stdint.h: Likewise.
	* sysdeps/gnu/utmpx.h: Likewise.
	* termios/termios.h: Likewise.
