Iguchi-san,
You are correct. The reference to foo with an integer argument is disambiguated
by the use of the keyword.
The only compiler that I have found that handles this correctly is DF5.0/6.0.

BTW, concerning the overflow flag, I think it comes from the sign cancellation:
the long constant -2147483648 is replaced its opposite, but the opposite is not
representable in a long, hence the overflow.

Sorry, my mistake, I should not have suggested this testcase: this optimization
is indeed fine (yet GCC 4.1 does not apply it). The following testcase i
int foo(int i)
{
char buffer[10];
return buffer[i];
}
does not warn about the use of uninitialized array buffer. While
int foo(int i)
{
char buffer[10];
return buffer[2];
}
does. Likewise for C++.
