Actually the whole point of the email is that the compiler DOESN'T
complain when I pass an X pointer to a void pointer. Is the compiler
broken? Its GCC 3.3 on FC2.

As I said previously, gpointer works without making the user do the
casting. I'm not sure you read my email well, because I didn't say I
wanted the language to do the work for me, I said I wanted ME to do the
work for the user by doing the cast inside the function.

While the headers would look "obscure" the code would be more readable
since there is less redundant code. Clearly "foo_do_action" is designed
to worth with foo objects only.
