annotate srogue/trader.c @ 304:e52a8a7ad4c5
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.
