Rounding issue. 0.6 can probably not be precisly represented in a float.
Perhaps it is .599999 or something similar. The "normal" way to get rid of
this problem is to round the number instead of truncate it. Rounding is
done by adding (for a whole number) .5. In your case you would want to add
0.05. This should produce the same number in all 3 compilers (though not
tested):

#include <stdio.h>
int main(int argc, char * argv[])
{
       double v = 0.6;
       printf("%d\n", int( ( v + 0.05 ) * 10.0));
       return 0;
}
