It's not been committed yet, has it? In any case,
seems like the days of SJLJ are numbered... (BTW,
I hadn't noticed the location lists changes to GCC
3.5/4.0 which imply the need to use the as-yet-unreleased
6.1 GDB for debugging - very cool though, for
debugging optimised builds.)

This thread:

http://gcc.gnu.org/ml/gcc-patches/2004-02/threads.html#01085

seems to conclude that we put in -fno-omit-frame-pointer
anyways for libjava since we depend on backtrace( ), which
in older libc-s (and on MinGW, BTW) uses the frame-pointer
to walk the call frames.
