I assume you want to diff these files with older versions of those
same files in another directory.  Otherwise, wildcards don't make any
sense in the context of `diff'.

If the above is indeed the case, use the `-x PATTERN' option of
`diff', like this:

	diff -x '*.o' -x '*.bat' -r old new

where `old' and `new' are the two directories you want to compare.
The above example causes `diff' to ignore .o and .bat files.

If your problem was with the quotes, please note that the way to pass
special characters verbatim to programs is explained in sections 16.2
and 16.3 of the DJGPP FAQ list.
