Busybox hasn't got "file". I agree reporting them isn't obviously<br>
useful, but I think I'm yanking the comment (or at least moving it to<br>
the checkin comment).<br></blockquote><div><br></div><div>i meant "busybox and toybox [when generating gzip data] leave those unknown/blank".</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
And while we're at it, in zip detection...<br>

A double typecast is never a good sign, but here we compile with<br>
-funsigned-char (for consistency across architectures) which toybuf[4]<br>
already _is_ an instance of so... what is this doing? Did they mean to<br>
typecast it to (signed char) and then... llvm complained maybe? Can the<br>
zip version be negative?<br>
