int C function

[Andrej Mitrovic]

I think this is a side-effect of the new function pointer fixes, where
you now can't implicitly convert an extern(C) function to an extern(D)
function by accident (and that's a good thing). But the problem is,
you can't define a function with a different linkage type inline as a
type parameter. You have to use an alias instead:

extern (C) int puts(const char* s);
alias extern(C) int function(const char*) FunPtr;

class X
{
    @property void tt(FunPtr xz)
    {
    }
}

void main()
{
    X x = new X();
    x.tt = &puts;
}

(sorry for reindenting, my script does that :p)
