Among many other errors I tripped over this:

   CC    target/kernel/primitives.o
cc1: warnings being treated as errors
In file included from ../kernel/primitives.c:25:
../kernel/internal.c:53: warning: cast from pointer to integer of  
different size
../kernel/internal.c:53: error: initializer element is not constant
../kernel/internal.c:53: error: (near initialization for 't[2]')

Corresponding code is:

#ifndef FCOMPILER
/* instead of pointing to an explicit 0 variable we
  * point behind the pointer.
  */
static ucell t[] = { DOCOL, 0, (ucell)(t+3), 0 };
static ucell *trampoline = t;
#endif

The warning goes away if I cast to (unsigned long) first, but the  
initialization error remains. In powerpc-elf-gcc 4.4+ this didn't  
surface.
Suggestions how to fix?
