__cxa_get_globals, etc. are exported from the library, so ABI is ok. But I see
your point, and have added forward declarations to bring cxxabi.h to bring the
API up to spec.
In addition, doing a quick scan of the export lists and cxxabi.h/etc. it
appears some new functionality has been added in the API without exporting it
in the ABI. Here are the fixes:
+CXXABI_1.3.6 {
+
+ __cxa_allocate_dependent_exception;
+ __cxa_free_dependent_exception;
+ __cxa_get_exception_ptr;
+ __cxa_call_terminate;
Note that __cxa_*_dependent_exception are not currently described in the EH
parts of the CXXABI. It seems likely that they should be.
