Is this behaviour peculiar to the djgpp gcc v1.09?

Under Linux gcc, cpp is invoked with both infile and outfile arguments.

Whenever I needed to redirect stderr under ms-dos I would use a tiny
program called e2o thus:
            e2o gcc myprog.c >messages

I understand that there are a number of similar programs available on
simtel-20 which will do such redirection for you, plus other bells and
whistles.
