Line 1206: 	/* preset errno in case returned size does not match */
         : 	errno = EPIPE;

I'm setting it on purpose before the statement, so that if a failure that sets errno precipitates a non-valid return size, then we see that error, otherwise the EPIPE falls through.  I guess it wouldn't matter if errno=EPIPE was put just before the return write... if that is what you meant?
