The following redefinition will solve problem (3), and could even be
adapted to solve problem (2):

(global-set-key "\M-!"
                (function
                 (lambda () (interactive)
                   (call-interactively 'shell-command)
                   (redraw-display))))

One problem that bugs me is how do you find the line number of the
crash when your code core dumps.  There must be a way that you can
write down the number eip=XXXXXXXX, and later type in that number to
find out the line of the crash.

The DJGPP FAQ is confusing at this point.  I am presently using printf
statements to locate crashes, but this method is cumbersome.

They're not stupid questions at all!
