Use 4DOS.

4DOS is a shareware (ASP, in fact) *replacement* for the MS-DOS and
DR-DOS command interpreters, that provides a *lot* of additional
features.  One of those features is the ability to pipe standard
error much as Unix allows you to.  In your previous example, what
you'd do is

     gcc -Wall -c prog.cc >& error.lst

">&" means "pipe stdout *and* stderr to a file".

4DOS does a *whole* lot more than this, though; IMHO it's the best
piece of shareware ever written.  You can get hold of it from the
usual SIMTEL archives, in the U.S. at least; I'm not sure what it's
European mirrors are.  My favorite U.S. site is oak.oakland.edu, in
the /pub/msdos/4dos directory.

Good luck!
