That's true, but some programs downcase file names before using them,
and don't differentiate between patterns and actual file names.
That's what Emacs does.  (I will fix this in Emacs in a day or two.)

Anyway, I think given the slim chances that there will ever be another
DJGPP release, I think this is a moot point.  Any changes in the
library at this time are unlikely to help DJGPP users.
