--- Comment #2 from Michael Haben <mh at ashwireless dot com> ---
"eh" being exception handling?
Is there any command-line switch that will turn off generation of this "tree"
thing in code that doesn't (and can't) use exceptions (e.g. ARM microcontroller
code, for which GCC is very widely used)?
Thanks, Mike H.
