Are you sure that's wise?  Altering djgpp.env can stop all djgpp 
programs from working, and it's hardly ever necessary.

Good question.  Does it matter though?  If your only intention is to
edit the djgpp.env file, you can use the environment variable DJGPP
which should point to it.  Note that if there's something wrong with
their DJGPP setting or djgpp.env file your program might not run,
because it will try to load the djgpp.env file.

Search the whole hard disk?  Remember though that it might not be on
a local disk, or someone might have two copies of djgpp installed. 
I don't think what you're asking makes a lot of sense -- it's like
asking how to find a game you've installed when you forget where you
put it.
