Yes, there's a program called 'doschk'. I can't remember if it's gnu or
non-gnu, but you can get from GNU FTP mirrors.

That would be very cool.

The problem is with unpacking the archive. The user will have to choose new
names for the conflicting files and then update tests/Makefile.am
appropriately. I hadn't considered what happens afterwards, but I think the
same test will be run multiple times.

This is not a problem for the actual DJGPP packages, since we have a way of
coping with it. The DJGPP archiver, djtar, allows you to specify a filename
change list (format: one line per file: old-name new-name) and renames files
as they are extracted. tests/Makefile.{am,in} as shipped in the DJGPP packages
are patched with the new names.

It would be nice for the automake tests to work "out of the box" with DJGPP
without renaming. But there are other more important issues to fix ("bigger
fish to fry"), to make it work well with DJGPP.

Ah. How about Cond.{pm,pl} and CondSet.{pm,pl}?

Thanks, bye, Rich =]
