REF_TO array is incorrectly generated

[Angus-Bethke-Bachmann]

Describe the bug
REF_TO array is incorrectly generated, see the below example.

To Reproduce
Following function in PLC:

FUNCTION Util_PackBitsToDWORD : ErrorCode
VAR_INPUT
    ValueRef: REF_TO ARRAY [*] OF BOOL;
    StartIndex: INT := 0;
    Length: INT := 32;
    Offset: INT := 0;
END_VAR
VAR_OUTPUT
    Result: DWORD;
END_VAR
END_FUNCTION

which is generated into:

void Util_PackBitsToDWORD(ErrorCode *Util_PackBitsToDWORD, __Util_PackBitsToDWORD_ValueRef_ *ValueRef,
                          int16_t StartIndex, int16_t Length, int16_t Offset, uint32_t *Result);

The second argument will then lead to:
error: unknown type name '__Util_PackBitsToDWORD_ValueRef_'.

Expected behavior
From the above example, I would expect a bool* ValueRef to be generated instead of the __Util_PackBitsToDWORD_ValueRef_ *ValueRef.
