missing "##" operator

[Michael Schmoock]

The ## is the pre-processor token pasting operator.The left token is appended with the right token.

example:

define DECLARE_HANDLE(name) struct name##__ { int unused; }; typedef struct name##__ *name

Should expand to:
struct HINSTANCE__ { int unused; }; typedef struct HINSTANCE__ *HINSTANCE;
