Proposed fix

The headers of the gmmproc generated C++ bindings contain forward references
like:

typedef struct _Type Type;
typedef struct _TypeClass TypeClass;


These conflict with C headers containining type definitions of the form:

typedef struct {
    ...
} Type;

typedef struct {
    ...
} TypeClass;


Replacing these with the following fixes the problem:

typedef struct _Type Type;
typedef struct _TypeClass TypeClass;

struct _Type {
    ...
};

struct _TypeClass {
    ...
};
