Well, could you be please more specific, what in the unwind-cxx.h is
causing especially your questioning here? As exactly the unwinding
requires that dtor is called for C++ with proper calling-convention.
Only thing I see, if we need instead of introducing here specific
_cxa_dtor_type marking existing type __cxa_cdtor_type optional by this
calling-abi attribute and replacing in libsupc++ the uses of 'void
(*)(void *)' by __cxa_cdtor_type.
