It isn't about "a broken port".  All C++ code is broken if exceptions
don't work.  That means devd is broken.  Not to mention clang itself.
 It may be that neither of those relies on exceptions for routine
operation and uses them only for error handling, and errors mostly
don't happen.  There is plenty of C++ code in the world where
exceptions are used in non-fatal-error cases and where the applications
just don't work at all without them.
