   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

   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:

 After the cross-configuration you type  
   
 make gforths  
   
 This produces the gforth engines for the target.  
   
 The next step is to transfer everything to the target; on the target,  
 you do  
   
 make  
   
 to complete building gforth.  If you do not have a make on the target,  
 run  
   
 make -n  
   
 on the host; manually execute on the target the last command output by  
 "make -n" (GFORTHD=...); the other commands output by "make -n" are  
 not necessary unless you have changed the Gforth sources.  You can  
 then check and benchmark Gforth with  
   
 make check  
 make bench  
   
 or equivalent.  Finally, perform  
   
 make install  
   
 or the equivalent commands on the target.
