I think the problem is that we don't look passed eh_spec_block trees.

The problem is that block_may_fallthru does not handle try_catch_expr and eh_filter_expr.

Hmm, I get a bootstrap failure with the patch:

And here is the reduced testcase for that failure:
void f(void);
void g(void) throw()
{
f();
}
I have to rethink this, maybe we should skip those trees before passing to block_may_fallthru.

All this code will go away for 4.1 anyways which is good (and we will not have false postives any more).
Anyways patch here: <http://gcc.gnu.org/ml/gcc-patches/2005-01/msg01675.html>.

I opened another PR because it is related but not fully the same problem. (PR 19699).

We still (as of CVS from Feb 8) get the warning if the throw-specifier is
not empty.
This example still gives the warning with -Wall -O1:
struct E{};
inline int bar() throw(E)
{
return 0;
}
void foo ()
{
bar();
}
