-You need gcc version 2.0 or later to compile gforth.  Recommended:
-gcc-2.95.* (other versions produce slower code).
+You need gcc version 2.0 or later to compile gforth.
 
-To use the new C interface, you need to install the ffcall libraries

+For the (documented) libcc.fs C interface you need a C compiler 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

+On many architectures (exceptions: 386, PPC, MIPS, Alpha) you need gdb

 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

 ac_cv_sizeof_char_p is the same as "sizeof(char*)" in C code. The
