STABS: Anonymous union importing issues

Lots of imported types contain this invalid type *__null__-1_-1:

As an example, take the VECTOR class.

The struct as emitted with the C exporter is:

struct VECTOR { // 0x10
    /* 0x0 */ union { // 0x4
        /* 0x0 */ AS3 as;
        /* 0x0 */ float x;
    };
    /* 0x4 */ float y;
    /* 0x8 */ float z;
    /* 0xc */ float gUnused;
};

Not sure if significant, but on import the following errors are printed:

STABS> Type lookup failed: FE
STABS> Type lookup failed: FE
STABS> Type lookup failed: FE
STABS> Type lookup failed: FE
STABS> Type lookup failed: ASO
STABS> Type lookup failed: rtx_def

This is fixed by #18.
