 configure has the following useful parameters:  configure has the following useful parameters:
 -direct-threaded: setup for a direct threaded interpreter; this is faster    --prefix=PREFIX         install architecture-independent files in PREFIX
    on many machines, but needs special support. Unsupported machines will                            [default: /usr/local]
    ingore this switch. On some CISC machines, direct threading isn't an    --exec-prefix=PREFIX    install architecture-dependent files in PREFIX
    advantage over indirect threading.                            [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.
   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.:
 -without-debug: omits the -g switch and creates smaller images on machines  env CC=gcc-2.7.1 ./configure
    where "strip" has problems with gcc style debugging informations.  
 --help: tells you about other parameters.  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:
 Now type  env "CC=gcc -b i486-linuxaout -V 2.7.0" ./configure
   After, configuration, type
 make  make
 If your make has trouble with the Makefile, "make gforth" might work.  Now you can check whether your shiny new Forth system works. Say
 If your installed gcc isn't called "gcc" (eg. called "gcc-2.6.1"), type  make test
 make GCC=<whatever you call your gcc>  You can run some benchmarks with
 instead.  make bench
 Now you can check whether your shiny new Forth system works. Say  and compare them with the results in Benchres and in the manual.
 make test  If everything is all right, you may want to install gforth. Type
 To make the documentation, type  make install
 make -k gforth.info gforth.ps html  You have to make an entry in the info directory file manually.
 If everything is allright, you may want to install gforth. Type  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 install  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, just concatenate the files
   gforth.info-* ('cat gforth.info-*' under Unix).
                   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/site-init.fs
   (if the commands work for all architectures) or
   /usr/local/lib/gforth/site-forth/site-init.fs (for
   architecture-specific commands);
   /usr/local/lib/gforth/site-forth/site-init.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/site-init.fs if there is no such
   If you change the site-init.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.
                           A Possible Problem
   You need to read this only if you see a message like
   "gforth: Cannot load nonrelocatable image (compiled for address 0x1234) at address 0x5678
   The Gforth installer should look into the INSTALL file"
   Gforth supports both relocatable and fixed-address images. If you load
   normal Forth code and save the image, you get a fixed-address
   image. Producing a relocatable image is more difficult.
   Therefore, Gforth has only a relocatable image of the kernel
   (kernal.fi), which is powerful enough to load the rest of
   Gforth. However, loading the rest takes a noticable amount of time. To
   avoid this delay (which would occur on every startup), the
   installation procedure produces an image fixed at an address
   determined at the Gforth run that produced the image. This
   fixed-address image is loaded by default. On most OSs this works,
   because the first chunk of memory is always allocated at the same
   address. If the address changes, you get the message above.
   An image address change can be caused by a change of the gforth
   executable, or by a change (upgrade) of the OS; in these cases you
   just have to rebuild and reinstall the fixed address image with
   rm gforth.fi; make gforth.fi; make install
 You may want to override the defaults for the directories. E.g., if  If you get such a message with a different address in place of the
 you want to install in the /gnu hierarchy instead of in the default  0x5678 each time you try to start gforth, you cannot use fixed-address
 /usr/local hirarchy, say  images on your OS. In this case, send us a message so that we start
   searching for a comfortable solution to this problem. In the
   meantime, start gforth with
 make install prefix=/gnu  gforth -i kernal.fi startup.fs
 Alternatively, you can specify the prefixes with configure.
