Presumably because C90 allowed return without a value in a function returning non-void, as long as the caller didn't use the return value (which in turn probably arose because in pre-standard C, people wouldn't use a void return type, they'd just omit the return type and let it be implicit int). Return without a value in a function returning non-void, implicit int and implicit function declarations are all things removed in C99 for which it may now make sense to enable warnings by default. -- Joseph S.
