New issue 244 by [hidden email]: unzip errors on .mcz files ,  
_decompressBytes fails
http://code.google.com/p/glassdb/issues/detail?id=244

 From the GemStone bug report:

Most of the .mcz packages that we have in CVS in
gss64bit/examples/monticello/repository
won't unzip cleanly. unzip reports "missing 1 bytes"

This causes the _decompressBytes primitive to fail when loading a .mcz file
and decompression falls back to the slower Smalltall implementation.

Example:

% unzip -l GsRandom-dkh.6.mcz
Archive: GsRandom-dkh.6.mcz
error [GsRandom-dkh.6.mcz]: missing 1 bytes in zipfile
(attempting to process anyway)

Looks like the following will do the trick (ZipArchive>>writeTo:):

writeTo: stream
        members do: [ :member |
                member writeTo: stream.
                member endRead.
        ].
        writeCentralDirectoryOffset := stream position - 1.
        self writeCentralDirectoryTo: stream.
