I *only* build with obj dir != src dir and never have a problem.

This looks like you didn't run configure in the build directory ?

That one's okay. If I could figure out how to turn the warning off, I
would. In any event, its not indicative of a problem.

Not sure what's up with that. 3.4 doesn't generate the warning and there
actually is not a way to return from that function by reaching the end.
The final statement is an if which either throws or returns. Looks like
3.5 has some regressions.

I think that's what the author intended. It doesn't give a warning with
GCC 3.4. If this troubles you, could you prepare a patch that doesn't
cause this file to generate the warning with GCC 3.5?

I have the same comment for everything below here too. Most of us don't
use GCC 3.5 (yet). I personally won't use it until 3.5.1 is available as
I don't like to waste my time with compiler flaws. So, if you'd like to
get rid of these warnings, the simplest solution is to use GCC 3.4.
Otherwise, you'll need to fix them yourself.
