: Hmm, I don't see any need for ELF_TARGET_SYMBOL_FIELDS.  Perhaps
: you'd like to get rid of ELF_TARGET_SYMBOL_FIELDS while you're at it.

   I would prefer to keep it in.  I use this definition of 
   TARGET_SYMBOL_FIELDS in my port (it's elf-based):

#define TARGET_SYMBOL_FIELDS ELF_TARGET_SYMBOL_FIELDS int my_sym_field;
