Newbie: Compiling Emacs 21.2 with MinGW

[Kai Grossjohann]

I'm trying to compile Emacs 21.2 (it's the most recent tarball I could
find,
emacs-21.3.tar.gz seems to be still down) with MinGW.  I have no
experience
whatsoever using Windows and MinGW...

Anyhow, I installed MinGW and MSYS.  I added c:\mingw\bin and
c:\msys\1.0\bin to %PATH%.  Then I went to the emacs-21.2/nt directory
and invoked:

    configure --prefix=c:\programme\emacs-21.2

It told me to run gmake.  I don't have gmake.  So I ran make instead,
which
gave an error.  Running make again gives the following output:

E:\src\emacs\emacs-21.2\nt>make

So, what do I do now?

Is it fixed in 21.3?  Then where can I get that?
