What do you mean by "installed by default"?  If we want the
instructions to be comprehensive, we need to spell out _all_ of the
packages, including those installed by default.

Why --without-all?  You do have the image libraries, right?

It's a bug (I didn't yet try to build outside of the source tree, so I
didn't hit it).  Change this line in nt/Makefile.in:

        ${WINDRES} -O coff -o emacs.res emacs.rc

to say this instead:

        ${WINDRES} -O coff -o emacs.res ${srcdir}/emacs.rc

Btw, you don't need to say "make bootstrap" with this setup, unless
you want to force a bootstrap.  Just "make" will do whatever it takes
to build Emacs, and will bootstrap if needed.
