You are confusing two different programming languages.

In C, gcc will produce a warning that 'main' is not declared returning
'int' and that's it.

In C++, 'void main' is treated as an error. gcc (2.8.1) -Wall -ansi
-pedantic _will_ tell you that it changed the return type of 'main' to
'int' and therefore it will consistently complain that you didn't
return an int.
