I had support for lists locally and just pushed it.  It is based on GSList and 
uses a marker to indicate the type.  So:

struct MyDevice {
      int32_t reg1;
      int32_t reg2;

      GSList _type_is(MyRequest) *pending_requests;
};

This is nice and works and extends to any list type but the syntax is awkward. 
So I also swizzled things so that we run through the preprocessor first such 
that we can do:

#define QSList(a) GSList _type_is(MyRequest)

struct MyDevice {
      int32_t reg1;
      int32_t reg2;

      QSList(MyRequest) *pending_requests;
};
