[4.1] Patch: FYI: ZipFile fixlet

[Tom Tromey <tromey@redhat.com>]

I'm checking this in.

Currently our ZipFile will fail if you try to get an entry whose name
contains a non-ASCII character.  The length check is incorrect... and
there's really no point to checking the length anyway, as we already
know the entry's name matches.

This is already fixed in Classpath.

	* java/util/zip/ZipFile.java (checkLocalHeader): Don't check name
	length.
