You know, I saw the title in the bug tracker and wondered if someone 
would pick on that. ;)

No. I usually append the directory of the executables to PATH and set 
the exec path accordingly in my .emacs. This is more portable than 
adding it to the path permanently on every computer. The setqs above 
were just to make it work with `emacs -Q'.

I need GNU find because otherwise Windows find complains about incorrect 
parameter format (maybe a separate issue?).

No. I pasted it into cmd.exe and it gives the exact same error.

Same result.

No. The spaces are not the problem. I enclosed the path in quotes so it 
finds the correct executable at this path (I omitted the quotes before 
and it would only find C:\Program).
