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.

rogue3/init.c
