The module which controls this is
 djgpp/src/libc/posix/glob/glob.c
It's included in the djlsr203.zip

Look at the variable "caseless" (in particular where it is set when the
name has upper case characters and use_lfn).

If you want proper downcasing of 8.3 names under Win2K, you can also grab 
the updated CVS source:
 http://www.delorie.com/bin/cvsweb.cgi/djgpp/src/libc/posix/glob/glob.c
but you will also need to grab the new _is_DOS83 routine:
