Right... my brain was on vacation when I wrote that. The below code
below will however handle non-power-of-two situations, etc.

main()
{
        int c = 1024*1024;
        int f = 3,g;
        
        while((c - f) > 1){
                g = (c + f) / 2;
                
                if(dup2(0,g) < 0)
                        c = g;
                else
                        close(f = g);
        }
        
        printf("maxfd = %d\n",c);
}
