If you really don't want to see those messages, the best way to do it is
to catch SIGINT within your program and have it simply exit.  Then you
aren't dependent on any compiler's particular ways.  Here's a basic
example that causes the program to simply exit whenever Ctrl-C or
Ctrl-Break is pressed:

#include <signal.h>

void SIGINT_handler( int signal )
{
    exit( 255 );
}

int main( void )
{
    signal( SIGINT, SIGINT_handler );

    ...
}
