o Minor bugfixes:
- Build using the -fasynchronous-unwind-tables option so that more
platforms (in particular, ones like 32-bit Intel where the
-fomit-frame-pointer option is on by default and table
generation is not) will support generating backtraces. This
doesn't yet add Windows support yet; only Linux, OSX, and some BSD
are affected. Reported by 'cypherpunks'; fixes bug 11047; bugfix
on 0.2.5.2-alpha.

dnl If we are adding -fomit-frame-pointer (or if the compiler's doing it
dnl for us, as GCC 4.6 and later do at many optimization levels), then
dnl we should try to add -fasynchronous-unwind-tables so that our backtrace
