Oops, it also affects Gecko builds with devel/libunwind installed
but not when port's GCC is used, e.g.

  $ fgrep _Unwind_Backtrace /usr/local/lib/gcc47/**/*.h
  /usr/local/lib/gcc47/gcc/x86_64-portbld-freebsd9.9/4.7.1/include/unwind.h:_Unwind_Backtrace (_Unwind_Trace_Fn, void *);

unwind.h in GCC doesn't hide the function under _GNU_SOURCE.
