It just isn't. That's about all about it anyone outside Redmond, WA,
US of A, will ever know.

Every remotely decent shell can do it. Which only serves to prove the
point that command.com isn't a decent shell. So, what else is new?

Because such a switch doesn't exist. It can't be made the default
behaviour of gcc to write error messages to stdout instead of
stderr. Not before all existing program that use a call like 'gcc -E
input > output' to C-Preprocess a file have vanished from existence.
You definitely don't want error messages redirected to file 'output',
in that case.

Anyhow: stderr is *there* for exactly the purpose of having a channel
to output error messages. Outputting error messages to stdout would be
a design violation, sort of. It's really command.com that is at fault
here, not GCC.

You only need a decent command line shell, or a little tool like
redir. Given the fact that redir.exe or a similar feature has been
coming with DJGPP for longer than most of the current users may be
able to remember, I fail to see any big problem, here.
