                   Prerequisites
   
 You need gcc version 2.0 or later to compile gforth.  You need gcc version 2.0 or later to compile gforth.
   
   For the (documented) libcc.fs C interface you need a C compiler and
   libtool at run-time.
   
   For the (undocumented ) lib.fs C interface you need to install either
   the ffcall libraries or the libffi library.  Libffi comes with recent
   gccs, ffcall can be found on
   
      ftp://ftp.santafe.edu/pub/gnu/ffcall-1.8.tar.gz (USA) 
      ftp://ftp.ilog.fr/pub/Users/haible/gnu/ffcall-1.8.tar.gz (Europe) 
   
   On many architectures (exceptions: 386, PPC, MIPS, Alpha) you need gdb
   at run-time in order for the disassembler to work.

   For MacOS X on Core 2 processors, you might want to use the 64-bit
   version for increased speed (more registers available); you have to
   ask for that on configuration, as follows:
   
   ./configure CC='gcc-4.2 -arch x86_64' --build=x86_64-apple-darwin9.4.0

 A few tests made by the configure script do not work in a  There is currently no simple way to do cross-installation of Gforth
   (apart from Gforth EC).  The current build process interleaves
   compiling and running heavily, so multiple transfers between build and
   target machine would be required.  We don't have a testing environment
   for cross-compilation, so we cannot fix this at the moment.  If you
   want to do cross-installation, please contact us.
   
   In any case, you might find the following useful:
   
   You need a cross-compilation toolchain for your target including gcc
   (2.0 or later).
   
   The first step in cross-installation is the cross-configuration.  A
   few tests made by the configure script do not work in a
 cross-compilation situation. You have to provide the results of these  cross-compilation situation. You have to provide the results of these
 tests by hand. E.g., if you compile for a 386 architecture processor:  tests by hand. E.g., if you compile for an ARM:
   
 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  env skipcode=".skip 16" ac_cv_sizeof_char_p=4 ac_cv_sizeof_void_p=4 \
