The Zip binary I use (compiled with DJGPP v2) stores the filenames in the 
same case as given on the command line.  It never downcases anything.  
Check out the zip files for Emacs distribution on DJGPP sites: they were 
produced by Zip.

This is *wrong* IMHO: I think Zip should not downcase the name even when 
it runs on plain DOS, where _USE_LFN is zero.  That is, unless the above 
fragment gets the filenames from a function such as `findfirst' which 
reports filenames in all-upper case.
