Forward reference fails when declaration is inside static if statement.

example:
//------------------------------------------------
const FOO_VER = 2;

static if(FOO_VER >= 2) // If Bar is defined
struct Bar {            // Foo should be defined too.
  Foo foo;
}

static if(FOO_VER >= 1)
struct Foo {
}
//------------------------------------------------

error: identifier 'Foo' is not defined
error: 'Foo' is used as a type
error: variable 'main.Bar.foo' voids have no value

The problem occurs for structures and classes, but not for functions:

The following work correctly:
//------------------------------------------------
static if(FOO_VER >= 2)
class Bar {
  this(){ func(); };
}

static if(FOO_VER >= 1)
void func(){ }
//------------------------------------------------
static if(FOO_VER >= 2)
void func(){ Foo foo; }

static if(FOO_VER >= 1)
struct Foo {
}
