For the effect of the program to be defined, the main function must return
a value.  It does seem strange that the compiler is required to issue a
diagnostic for a return statement with a value in a void function, but not
for the opposite mistake.

OK, if you don't want your program to send a small nuclear device at your car,
the main function must return a value.  (2.1.2.2 neither allows nor disallows
this extreme an effect; 3.6.6.4 allows it.)
