Note that function prototypes are not included in this code - remember to add
them to merc.h yourself - also add the 'second' command to interp.c.
Secondary weapon code prototype. You should probably do a clean compile on
this one, due to the change to the MAX_WEAR define.
Last update: Oct 10, 1995
Should work on : MERC2.2
