early-roguelike/srogue/things.c
John "Elwin" Edwards 6c3cd116ff Fix many compiler warnings. 
There should only be two changes in behavior:

arogue7/fight.c, arogue7/fight.c: a to-hit bonus is now correctly
applied to characters who are not monks instead of monks who are not
empty-handed.

urogue/fight.c: fixed an interaction with the "debug" macro that could
cause the wrong message to be displayed.
