    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
   hirarchy, say
   
 -without-debug: omits the -g switch and creates smaller images on machines  ./configure --prefix=/gnu
    where "strip" has problems with gcc style debugging informations.

   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
   
 make install prefix=/gnu  gforth -i kernal.fi startup.fs
   
 Alternatively, you can specify the prefixes with configure.
