foo.cc: 3: warning: return type of 'main' defaults to 'int'
foo.cc: 6: warning: return with no value in function not returning 'void'

(Strangely enough egcs fails to emit either of these with -Wall, but it
should and IIRC gcc 2.8.x does if you define a function like that... egcs
just silently outputs an 891 byte .o file as though that were a well-formed
program!)

Because he made a mistake :-) It should return 'int'.
