Can somebody explain to me why normal C code compiled with  G++ is
smaller in size than when I compile it with GCC ?

For example, this very original program:

    #include <stdio.h>
    int main(void)
    {
        printf( "Hello world!\n" );
        return 0;
    }

compiles into a 6532 bytes 'big' executable using `gcc main.c`.
(After stripping.)
Using g++ it's only 3032 bytes of size.


I also had the feeling that the pgcc compiler generates larger
code than gcc-2.7.2. Is that all because of the optimization?
