Well...I did some digging around and found that I could get what I want by

1) turning on the __OPENDIR_PRESERVE_CASE flag for the DJGPP opendir()
   function in the djlsr200.zip file and

2) disabling the dosify() function in the dir.c file in the mak373s.zip
   distribution.

So, I came up with these patches (probably mangled in transmission and not
formatted to "standards", but anyways) to add support for a PRECASE
variable (like the LFN variable you can set in DJGPP.ENV) in DJGPP and to
add a NO_DOSIFY cpp define for make-3.73.
