 Very preliminary version  
 You need gcc version 2.0 or later to compile gforth.  You need gcc version 2.0 or later to compile gforth.
 Create a machine description file for your machine, if necessary.  First, type
 Make a symbolic link to machine.h, e.g.  (see Section Configuration Options below for details).
 ln -s decstation.h machine.h  After configuration, type
 Make a symbolic link from mach32l.fs or mach32b.fs to machine.fs  make
 Edit the Makefile (in particular the SWITCHES variable)  Now you can check whether your shiny new Forth system works. Say
 Now you can type  make test
   You can run some benchmarks with
   make bench
   and compare them with the results in Benchres and in the manual.
   If everything is all right, you may want to install gforth. Type
   make install
   You have to make an entry in the info directory file manually (see
   Installing Info Files, below).
   For paper documentation, print gforth.ps (a Postscript file (300dpi
   fonts, i.e., it works, but does not produce best quality on better
   printers)), or say
   make gforth.dvi
   and print the resulting file gforth.dvi. You can also get the
   documentation in HTML format by typing
   make html
   If you prefer plain ASCII documentation, you can 
   make doc/gforth.txt
   or just concatenate the files gforth.info-* ('cat gforth.info-*' under
   Unix); the result of the latter option is a little worse.
   You can find binary distributions, documentation in HTML and plain
   text format and information on known installation problems at
                   Configuration Options
   If you use GNU make, you can build in a directory different from the
   source directory by changing to the build directory and invoking
   configure thus:
   where $srcdir is the source directory. (Note that we tested this only
   for installation; i.e., if you want to hack the Gforth sources, you
   should probably build in the source directory).
   configure has the following useful parameters:
     --prefix=PREFIX         install architecture-independent files in PREFIX
                             [default: /usr/local]
     --exec-prefix=PREFIX    install architecture-dependent files in PREFIX
                             [default: same as prefix]
     --enable-force-reg      Use explicit register declarations if they appear in
                             the machine.h file. This can cause a good speedup,
                             but also incorrect code with some gcc versions on
                             some processors (default disabled).
     --enable-direct-threaded      Force direct threading. This may not work on
                                   some machines and may cause slowdown on others.
                                   (default processor-dependent)
     --enable-indirect-threaded    Force indirect threading. This can cause a
                                   slowdown on some machines.
                                   (default processor-dependent)
     --with-debug     specifies option -g to compile with debug info (default)
     --without-debug  omits the -g switch and creates smaller images on
                      machines where strip has problems with gcc style
                      debugging informations.
     --help: tells you about other parameters.
   The file Benchres shows which combination of the -enable options we
   tried gave the best results for various machines.
   If you don't like the defaults for the installation directories, you
   should override them already during configure.  E.g., if you want to
   install in the /gnu hierarchy instead of in the default /usr/local
   hierarchy, say
   ./configure --prefix=/gnu
   Moreover, if your GCC is not called gcc (but, e.g., gcc-2.7.1), you
   should say so during configuration. E.g.:
   env CC=gcc-2.7.1 ./configure
   You can also pass additional options to gcc in this way, e.g., if you
   want to generate an a.out executable under Linux with gcc-2.7.0:
   env "CC=gcc -b i486-linuxaout -V 2.7.0" ./configure
   You can change the sizes of the various areas used in the default
   image `gforth.fi' by passing the appropriate Gforth command line
   options in the FORTHSIZES environment variable:
   env "FORTHSIZES=--dictionary-size=256k --data-stack-size=16k --fp-stack-size=15872b --return-stack-size=15k --locals-stack-size=14848b" ./configure
   The line above reaffirms the default sizes. Note that the locals
   stack area is also used as input buffer stack.
   If C's "long long" do not work properly on your machine (i.e., if the
   tests involving double-cell numbers fail), you can build Gforth such
   that it does not use "long long":
   env ac_cv_sizeof_long_long=0 ./configure
   A few tests made by the configure script do not work in a
   cross-compilation situation. You have to provide the results of these
   tests by hand. E.g., if you compile for a 386 architecture processor:
   env ac_cv_sizeof_char_p=4 ac_cv_sizeof_short=2 ac_cv_sizeof_int=4 ac_cv_sizeof_long=4 ac_cv_sizeof_long_long=8 ac_cv_c_bigendian=no ./configure
   The ac_cv_sizeof_... variables give the sizes of various C types;
   ac_cv_sizeof_char_p is the same as "sizeof(char*)" in C code. The
   ac_cv_c_bigendian variable gives the byte order.
                   Preloading installation-specific code
   If you want to have some installation-specific files loaded when
   Gforth starts (e.g., an assembler for your processor), put commands
   for loading them into /usr/local/share/gforth/site-forth/siteinit.fs
   (if the commands work for all architectures) or
   /usr/local/lib/gforth/site-forth/siteinit.fs (for
   architecture-specific commands);
   /usr/local/lib/gforth/site-forth/siteinit.fs takes precedence if both
   files are present (unless you change the search path). The file names
   given above are the defaults; if you have changed the prefix, you have
   to replace "/usr/local" in these names with your prefix.
   By default, the installation procedure creates an empty
   /usr/local/share/gforth/site-forth/siteinit.fs if there is no such
   If you change the siteinit.fs file, you should run "make install"
   again for the changes to take effect (Actually, the part of "make
   install" starting with "rm gforth.fi" is sufficient).
                   Multiple Versions and Deinstallation
   Several versions of Gforth can be installed and used at the same
   time. Version `foo' can be invoked with `gforth-foo'. We recommend to
   keep the old version for some time after a new one has been installed.
   You can deinstall this version of Gforth with 'make uninstall' and
   version foo with 'make uninstall VERSION=foo'. 'make uninstall' also
   tells you how to uninstall Gforth completely.
                   Installing Info Files
   Info is the GNU project on-line documentation format. You can read
   info files either from within Emacs (Ctrl-h i) or using the
   stand-alone Info reader, 'info'.
   If you use the default install root of '/usr/local' then the info
   files will be installed in '/usr/local/info'.
   Many GNU/Linux distributions are set up to put all of their
   documentation in '/usr/info', in which case you might have to do a
   couple of things to get your environment set up to accommodate files
   in both areas:
   1. Add an INFOPATH environment variable. The easiest place to do
   this is '/etc/profile', right next to PATH and MANPATH:
   2. Create a file called 'dir' in 'usr/local/info'. Use the file
   '/usr/info/dir' as a template. You can add the line for gforth
   manually, or use '/sbin/install-info' (man install-info for details).
