[Issue 2626] template function not working against template struct instantiated with default arguments

Here's a simpler version, but fixing it isn't:

struct S(int x = 1){}

void fun()(S!(1) b) { }

void main()
{
S!() s;
fun(s);
}

[Issue 2696] New: Spurious ifclause of template function shown in error message

   Summary: Spurious ifclause of template function shown in error
message
   Product: D
   Version: unspecified

(Thanks CLXX for submitting this to the newsgroup.)

void fun(T)(T t) if (is(T == string)) {}
void fun(T)(T t) if (is(T == int)) {}

void main( ){
fun(1.0);
}

yields the errors:

./test.d(5): template test.fun(T) if (is(T == string)) does not match any
function template declaration
./test.d(5): template test.fun(T) if (is(T == string)) cannot deduce template
function from argument types !()(double)

The if (...) clause is superfluous as the compiler seems to print there
whatever fun overload was first in the module. The correct error message is:

./test.d(5): template test.fun(T) does not match any function template
declaration
./test.d(5): template test.fun(T) cannot deduce template function from argument
type !()(double)

Notice the grammar fix too :o).

If the ulong and long cases are removed, the cast to uint gives 2048.
Seems to be only float that has the problem - it disappears if I change it to
double or real.
