In stubs.c I added a dummy return to functions that were non void types.

in readfile.c I renamed some localvars that were named main to mainl in
a couple of functions.

in action.c I initalized a var to 0.  This is probably not needed but
its a little safer incase someone adds more modes...
I've included a diff of this last one below.
