[PATCH] D53127: Fix declaration of _URC_FATAL_PHASE1_ERROR in libc++abi when compiled with libsupc++ (follow-up of D42242)

I'm not sure I understand this patch.  Building libc++abi with libsupc++ doesn't make sense.  They are both providing the same API.  Are you trying to build against libgcc?  The GNU Savannah libunwind as well as the LLVM libunwind provide the definitions AFAICT.  libgcc has the definition in `unwind-common.h`.



================
Comment at: src/cxa_personality.cpp:1112
     bool is_force_unwinding = state & _US_FORCE_UNWIND;
-    state &= ~_US_FORCE_UNWIND;
+    state = (_Unwind_State)(state & ~_US_FORCE_UNWIND);
 
----------------
Unnecessary change?
