Here is a response from David Korn (yes, author of the Korn Shell 93):
> uwin-base.2013-02-08.win32.i386.exe is an executable that is a version of
> pax followed by the pax file.  The first thing that it does is seek to
> the byte location of the pax file and the executable portion of
> uwin-base.2013-02-08.win32.i386.exe then reads this file.

> It looks as if seeking to a byte location in uwin-base.2013-02-08.win32.i386.exe
> isn't working in wine.

How can I debug this situation?
