Nathan,
Just tested unzip on a particular .exe archive and it works. I
think the problem may be with .exe archives that are not following
the .zip specification. For example, I think most of Microsoft's
installs (self-extracting .exe files) are not .zip compliant. I was
testing various Microsoft downloads I have and am seeing the message
host% unzip -l vs6sp5.exe
Archive: vs6sp5.exe
End-of-central-directory signature not found. Either this file is
not a zipfile, or it constitutes one disk of a multi-part archive.
In the latter case the central directory and zipfile comment will be
found on the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of vs6sp5.exe or
vs6sp5.exe.zip, and cannot find vs6sp5.exe.ZIP, period.
So, in the case of these pernicious archives, unzip clearly won't
work. I have access to Microsoft machines so I never had to pursue
a FreeBSD solution. Sorry.
