Thanks. What about const and unsigned parameters?
So far, I've imported stuff like

int foo(const char *bob, unsigned int hope) {

as

extern int foo(char *, int);

However, I fear that some arithmetic (division?) on a variable before
passing it to foo might get me some big bad ugly bug one day that will
be near impossible to track down.
