test.c:113: return type for `main' changed to `int'

==============================

the G++ compiler gives this error, when I have main()
returning a typedef'd int.

I do not think this should be even a warning.  I am using
no native types in my software system, because I want to
be able to port my software easily.  However, -Wmain will
always complain that "main" has a suspicious type.  However,
there is nothing suspicious about a type of "int" which 
happens to be a typedef.
