 Very preliminary version  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.  ./configure
   
 ln -s decstation.h machine.h  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.
   
   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
   hirarchy, say
   
 Make a symbolic link from mach32l.fs or mach32b.fs to machine.fs  ./configure --prefix=/gnu
   
 Edit the Makefile (in particular the SWITCHES variable)  After, configuration, type
   
 Now you can type  
   
 make  make
   
   If your make has trouble with the Makefile, "make gforth" might work.
   
   If your installed gcc isn't called "gcc" (e.g., called "gcc-2.6.1"), type
   
   make GCC=<whatever you call your gcc>
   
   instead.
   
   Now you can check whether your shiny new Forth system works. Say
   
   make test
   
   To make the documentation, type
   
   make -k gforth.info gforth.ps html
   
   If everything is allright, you may want to install gforth. Type
   
   make install
   
   You have to make an entry in the info directory file manually. Also,
   you have to install gforth.ps and html yourself.
   
   
   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 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.
   
   Consequently, 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 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
   
   If you get such a message with a different address in place of the
   0x5678 each time you try to start gforth, you cannot use fixed-address
   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
   
   gforth -i kernal.fi startup.fs
