Subject: [PATCH] Work around broken integration with latest libc++. (#1635)
|
||||
|
||||
* Work around broken integration with latest libc++.
|
||||
|
||||
In newer versions of libc++, the base template of std::iterator_traits
|
||||
provides a member typedef called __primary_template which is an alias
|
||||
to the std::iterator_traits specialization itself. This fix works with
|
||||
both the old version of libc++ and the new one.
|
||||
|
||||
Fixes issue #1633.
|
||||
|
||||
* Fix is_std_iterator_traits_specialized_v on MSVC
|
||||
|
||||
It used to pretend that std::iterator_traits<T*> is a user-defined
|
||||
specialization, which isn't the case. This is due to MSVC's
|
||||
iterator_traits<T*> specialization not posing as the base template.
