Gilles, My patch is not merged on minizip101g. is it?

I make a patch again for minizip101g.
The patch avoid to over-write "err" from "ZIP_ERRNO" to "ZIP_OK".
When disk-full or other I/O error occurs, zipFlushWriteBuffer() returns
"ZIP_ERRNO", and deflateEnd() returns "ZIP_OK".
In this case, the error is lost and Minizip will make a broken zip file with
"ZIP_OK".
