Are nested variable-length vector fields in structures not supported?

module TestModule {
    struct TestStruct {
        // Cases 1 and 2: compile error
        UInt32 aNestedVectorField[];
        //UInt32 aNestedVectorField[length];

        // Case 3: no error
        //UInt32 aNestedVectorField[1];
    };
    config TestStruct aConfig = { aNestedVectorField: [ 42 ] };
}

package/cfg/xdctest_p86U.c:599:1: error: unknown type name '__T1_xdctest_TestModule_aNestedVectorField'
 const __T1_xdctest_TestModule_aNestedVectorField xdctest_TestModule_aConfig_aNestedVectorField__A[1];

The type that does exist (and seems to be the what the generator really means) is: __T1_xdctest_TestModule_TestStruct__aNestedVectorField. Manually typedefing the non-existant __T1_xdctest_TestModule_aNestedVectorField to __T1_xdctest_TestModule_TestStruct__aNestedVectorField allows the compilation to succeed.

Alexei, it's the same bug as in https://www.eclipse.org/forums/index.php/t/808339/. I have it on my list of things to do, but I haven't find the time until now. I'll post again when I have a better idea how much of an effort is to fix it.
