Succ, Osucc, Adrop

Hello, I've searched everywhere for an answer to this but I can't find it anywhere.
I'm running PennMUSH Server on my WinXP machine and I'm using it till I can find a proper server.

I've been building rooms and links but all my exits keep saying they are missing success messages (@succ, @asucc and @odrop) and I don't want to give them any. How do I turn off the need for them?
Also, how do I turn off the need for a returning exit?

Take a look at warnings.c. If you turn off USE_WARNINGS define, then the warnings code is not done.
