General setup_trampoline() idea is fine with me. Please avoid  
indentation changes though, you're replacing single tabs with 8 spaces.

Are you sure it doesn't need to be initialized from anywhere else,  
like load_dictionary() or forth_init(), for the initialization to take  
effect before any of these?

Will check.

You are aware that there is no dependency rule for internal.c since it  
is #included from primitives.c? You either need to do `make clean`  
first or reconfigure for changes to take effect.
