This looks like either Emacs on Mingw gets mixed up between the subprocesses'
stderr and stdout.  Or compile gets mixed up with its process marker (where
the process writes into the buffer).

Since this apparently only happens on Mingw, which I don't have, I don't know
where to start looking.  As per etc/MACHINES Mingw is not even a supported
plattform for Emacs...  I dare not even hope you have Cygwin, to see if the
same thing happens there?

This comment only pertains to one deprecated function.  I don't assume you
have used that function, but from the Recent input section below, I can't
determine what you did.

I'm not aware of having dropped any matchers.  The old compile.el didn't
mention EDG as one of the things it matched.  Maybe you had some extra
configuration from somewhere.  If you can send me a list with various kinds of
messages from this compiler (fatal, error, warning, info ... as available),
I'll try to match them.
