I am not against the change, but are you sure memcpy(3) has any chance
to change errno? I think it would actually be a bug if it does, since it
is not meant to fail, and it is a pretty essential component for error
recovery (writing messages...).
This is not a definite answer but:
$ find NetBSD/src/common/lib/libc -name memcpy.S -exec grep errno {} \+
does not report anything.
Anyway, HTH,
