The below code produces a zip file that can be opened in WinZip 8.1 when
compiled with Sun JRE 1.4.1_01.  When compiled with GCJ 3.4.0 the zip file is
produced but WinZip says it's corrupt.

Is this a bug in GCJ or am I misunderstanding how java.util.zip works in libgcj?

Thanks.

Usage:  Pass in two arguments to class.  First arg is name of archive and second
is the name of the file you want to add to the archive.
