Is there any language that native-compiles faster than D?

Pardon me, but that code seems everything but remotely
representative to me - no structs, no classes, no control flow,
just a few integer additions and calls. It even seems to make D
look worse than it is, simply because object.d is imported but
totally unused. E.g., on my Win64 box with DMD 2.093, compiling
this:
-----
int add_int_n0_h0(int x) { return x + 15440; }
int add_int_n0(int x) { return x + add_int_n0_h0(x) + 95485; }
int add_int_n1_h0(int x) { return x + 37523; }
int add_int_n1(int x) { return x + add_int_n1_h0(x) + 92492; }
int add_int_n2_h0(int x) { return x + 39239; }
int add_int_n2(int x) { return x + add_int_n2_h0(x) + 12248; }
int main()
{
int int_sum = 0;
int_sum += add_int_n0(0);
int_sum += add_int_n1(1);
int_sum += add_int_n2(2);
return int_sum;
}

with `dmd -o- bla.d` takes about 37ms, while creating an empty
object.d and compiling with `dmd -o- bla.d object.d` takes 24ms.
There's no default includes for C, so this would make the
comparison more fair.
Additionally, generics and templates are completely different
concepts and can't be compared.
