That is exactly what I had in mind.  The zip should include
configure.bat, not configur.bat.  Then, when you unzip it on non-LFN
platform, you get configur.bat which will work (since non-LFN
platforms silently truncate excess characters), while on LFN
platforms, Make will find the full-length configure.bat and be happy
also.

That's why I said that the _zip_ file is not LFN-clean.

IMHO, this is the wrong way of achieving the goal.  The file names
should be stored with their full length in the zip file, not
truncated.  If you truncate them, you will need to make too many
changes in the Makefile, which might be a pain when you use the
original Unix Makefile with minimal changes.

It won't work for every package.  Don't forget that Makefiles and
batch files sometimes call DOS commands like `copy', `ren' etc., and
these don't know about the LFN variable.  They always expect to see
the long file names.

So the only way to make it work on both types of systems is to make
the zip file store long file names which don't conflict when they are
unzipped on non-LFN machine (for example Makefile.in.in should be
stored as Makefile.in-in).
