Actually, it's the backslash that's causing the main problem (see the error 
message). 
avrdude comes from a unix/linux background where only forward slashes are used 
to 
delineate directory paths.

However, The issue with using Windows drive letters needs to be checked out to 
see 
if they're even being handled at all. .... And, now that I think of it, I need 
to check if 
spaces in the pathname are handled at all too.
