This only work with Pro*C if you run it in full parse mode. That means Pro*C
will parse your complete C file an not just the EXEC SQL parts. I would not
recommend doing this. At first glance it looks like a nice feature but you
can run into numerous sorts of trouble.

Yes, that's the standard way of doing this.

No, there is none. The full parse mode has been on my todo list for a long
time but with very low priority. Sorry.
