Update.

1999-01-23  Ulrich Drepper  <drepper@cygnus.com>

	* nss/nss_files/files-XXX.c (internal_getent): Make sure the buffer has
	at least two bytes (not one).  Correct buflen parameter type.
	* nss/nss_files/files-alias.c (get_next_alias): Make sure buffer
	has at least two bytes.  Use fgets_unlocked instead of fgets.

	* ctype/ctype.h: Don't user __tolower directly for tolower
	implementation.  Use inline function which tests for the range
	first.  Make _tolower equivalent to old tolower macros.
	Likewise for toupper.
	* ctype/ctype.c: Change tolower/toupper definition accordingly.

	* argp/argp-help.c: Use _tolower instead of tolower if possible.
	* inet/ether_aton_r.c: Likewise.
	* inet/ether_line.c: Likewise.
