New Revision: 308100
URL: https://svnweb.freebsd.org/changeset/base/308100

Log:
  compile libunwind c source with -fexceptions
  
  When an exception is thrown the unwinder must unwind its own C source
  (starting with _Unwind_RaiseException in UnwindLevel1.c), so it needs to
  be built with unwinding data.
