The message means that main itself should be returning a value, because it
wasn't declared to be of type void.  (So it defaults to type int.)  I think
this is ANSI-like behavior, and it's one of the warnings that can be turned
on or off.  I suppose that your three machines happen to have different
turboc.cfg/tcconfig.tc (where did they get such mismatched names?) defaults.
