Thanks for this. Upload on it's way to Clio as I write this

Check out the thread regarding the rm.exe issue I found as it looked like an
inode problem, but turned out to be something else.

I used the updated find.exe which included the patch and my results are as
follows:

Tried this on an ancient Win98 PC and got the following:-
1) cannot touch a directory get permission denied (EACCESS) error
2) I get an error from rm as follows (re-typed)
    rm: invalid operation -- .
3) $ find . -name '[Dd][Oo][Nn][Ee]'
    returned "./done" which looked okay.

I copied bash.exe, find.exe, rm.exe into the temp directory on the Win98 PC
and set the path to be c:\temp only. It works on XP with the same binary
files. Any ideas on this?

On XP with SP1 I get the following results:
a) Under bash:
    bash-2.05b$ find . -name '[Dd][Oo][Nn][Ee]' -exec rm -f '{}' ';'
    rm: `./done' is a directory
b) Under command.com or cmd.exe
    DJGPP_204 C:\dj204\bin>find . -name '[Dd][Oo][Nn][Ee]' -exec rm -f '{}'
';'
    rm: `./done' is a directory
