there should be no warnings; on older and on non-GNU systems the
generated warnings may still be useful.

The `--prefix=PREFIXDIR' option specifies where the installation process
should put emacs and its data files. This defaults to `/usr/local'.
- Emacs (and the other utilities users run) go in PREFIXDIR/bin
`src/config.h', and change the two `#include' directives to include
the appropriate system and architecture description files.
-2) Edit `./src/config.h' to set the right options for your system. If

3) Create `Makefile' files in various directories from the
corresponding `Makefile.in' files. This isn't so hard, just a matter
of editing in appropriate substitutions for the @...@ constructs.
