Hopefully I got all the editing right in change 23554 ( http://public.activestate.com/cgi-bin/perlbrowse?patch=23554 ) Unfortunately the testdrive systems seem to be unreachable, so I couldn't actually test anything. > We could get fancier with the mv, but I don't know exactly what > mv-if-diff does.

I wasn't clear. That was based closely on the existing section of the Unix Makefile. I'd not checked carefully enough to see what VMS was doing for that step. It's only Unix that's doing that mv-if-diff Anyway, change 23554 is now in, and with luck won't break on VMS or Windows (or anything Unix for that matter) Nicholas ClarkThread Previous | Thread Next
