And windows shows them as upper case in file manager/windows explorer?

Your other software is what I was referring to - which you've now
described - thanks.

I can't guess why cygwin is showing different from windows - it uses
windows calls to get the filenames. You may need to pick an example file
and use strace to see if any hints turn out. First off though, I'd
double check that *windows* - not command.com/cmd.exe thinks the file
really is lower case.

Yes yes - thats what you said the first time!
