Does constness count as a type difference in rule 11.2?

[fpeelo]

typedef struct s_EthBuf *TEthBuf;
typedef struct s_EthBuf const *CTEthBuf;

Sorry, that latter type should have been

typedef const struct s_EthBuf *CTEthBuf;

It's for rule 8.13

But whichever way around it's put, PC-Lint still recognises TEthBuf and CTEthBuf as distinct types, so a function with a parameter TEthBuf cannot pass it to a function which takes CTEthBuf, or const struct s_EthBuf *
