member fields for anonymous structures

[GlenCFL]

Anonymous structures, within something like a named union, seem to be stripped of the member fields that would otherwise be present in a named structure.

Generating XML from:

namespace test {

// union test
union v2 {
    // subscripting
    float values[2];
    // x, y
    struct {
        float x, y;
    };
    // a, b
    struct {
        float a, b;
    };
};

}

The generated contents of "test.xml" would be:

<?xml version='1.0' encoding='utf-8'?>
<namespace id="test" name="test" xmlns="http://jessevdk.github.com/cldoc/1.0">
  <union id="test::v2" name="v2">
    <brief>union test</brief>
    <struct name="(anonymous::1)" ref="test::v2::(anonymous::1)#test::v2::(anonymous::1)">
      <brief>x, y</brief>
    </struct>
    <field id="test::v2::values" name="values">
      <brief>subscripting</brief>
      <type size="2">
        <type builtin="yes" name="float" />
      </type>
    </field>
  </union>
</namespace>

Two issues with this:

• the second structure has vanished
• the anonymous structure that did make it through has no field elements

These two issues compounded makes it impossible to document the existence of these fields using the generated XML. Fixing the first allows documentation of the fields using comments/brief, though that's a bit hacky.

Should be fixed. Please feel free to reopen if the problem still persists.
