Ignore me. It was obvious in the code you gave that you are indeed correctly
closing the file after writing it.

Since the zipfile format is binary, you should *not* be running Unix2DOS to
convert it - you are probably messing up the file format by doing that, and
may well find everything works fine if you just transfer the file across to
Windows as a binary image.

Unix2DOS will translate LF in the input into CR/LF in the output. WinZip (or
whatever) won't expect that, and your file will be hosed. The file that
works possibly just doesn't compress down to something containing newlines.
