Thank you, but there were some additional bits for as/config/tc-m68k.[ch]
which I submitted in a later patch.  Could you please apply these too?

Here it is, separated from the rest and updated to current CVS:


2004-01-02  Bernardo Innocenti  <bernie@develer.com>

	* config/tc-m68k.h (EXTERN_FORCE_RELOC): Add special handling for
	uClinux.
	* config/tc-m68k.c (relaxable_symbol): Use EXTERN_FORCE_RELOC instead
	of hard-coded test for TARGET_OS=elf.
