Sorry about that.

Hmmm... Something is fishy here if this is a problem...

While the above is a valid (temporary) "fix",
I think rather than re-introducing this clause:

    (CONFIG_COMMANDS & CFG_CMD_SETGETDCR)

a better (long term) solution is to try and figure out
why CONFIG_CMD_SETGETDCR isn't available.  The goal is
to eliminate the CONFIG_COMMAND symbol, so we should
be able to compile this file without it.

My guesses off the top of my head:

    1) I blitzed CONFIG_CMD_SETGETDCR in the 4xx.h config file
    2) The 4xx board config file isn't being included here
    3) Interaction with a .S file
    4) Some secondary #include effect making config_cmd_default.h
       be not included

Please let me know if I can further here.

HTH,
