To compile emacs, you will need SAS C 5.10b. If you try to make it work
with Aztec C or gcc, you might run into difficulties with the dumping code:
- The "small" data model (A4-relative) is used, to get all the variables
  in one hunk.
- Some variables are declared with the "far" attribute to get them out
  of this hunk (and the dumping code depends on this). Move these to
  the amiga_data.c module (which is for variables that shouldn't be
  dumped).
You will also need my 'unix compatibility' library which should have been
distributed alongside emacs.

To compile:

a) Install the 'unix compatibility' library.

b) Install as usual (see INSTALLATION).

c) Compile the C preprocessor (SAS's one has problems ...):

     cd gnuemacs:cpp
     lmk

   When the preprocessor is running, it needs to find uncompacted versions
   of the include files. If you only installed the compacted include files,
   you will have to install the uncompacted ones somewhere.

   You can check your type of include files by looking to see if (eg)
   include:stdio.h is a readable text file (all is ok) or contains binary 
   characters (you have the compacted files).

d) Define cpp-include: to point to the uncompacted include files. If you forget
   this, you won't get a requester ...

e) Compile & dump emacs

     stack 20000
     cd gnuemacs:src
     lmk
     copy temacs /

   (This takes around 20 minutes from scratch on an A2500/30).

If all goes well, you should have a new version of emacs ...
