+ * libc/stdio/putw.c (putw): Return 0 on success, to be compliant
+ with XSH5, not SVID.

* libc/include/string.h: Changed last argument back to ssize_t
to write a word to the file or stream identified by <[fp]>. As a side
effect, <<putw>> advances the file's current position indicator.
-RETURNS The written word, unless the host system reports a write
-error, in which case <<putw>> returns <<EOF>>. Since <<EOF>> is a
-valid <<int>>, you must use <<ferror>> or <<feof>> to distinguish
-these situations when writing the integer equal to <<EOF>>.
+RETURNS Zero on success, <<EOF>> on failure.
PORTABILITY
<<putw>> is a remnant of K&R C, it is not part of any ISO C Standard.
