It has already been noticed that there are 2 ebo helpers in the lib. Here
is a patch to use 1.
* include/bits/ebo_helper.h: New.
* include/Makefile.am: Add latter.
* include/Makefile.in: Regenerate.
* include/bits/hashtable_policy.h: Adapt.
* include/bits/shared_ptr_base.h: Adapt.
Tested under linux x86_64.
Ok to commit ?
I don't think we support [[no_unique_address]] yet, but assuming we soon
will and we enable it also for C++03 (at least with the __attribute__
syntax and/or in system headers), do you know if some similar helper will
still be necessary, with a simpler implementation, or if the attribute
will magically get rid of it?
(I haven't looked at it at all, the answer may be obvious)
