Enforce allocator::value_type consistency for containers in C++2a
In previous standards it is undefined for a container and its allocator
to have a different value_type. Libstdc++ has traditionally allowed it
as an extension, automatically rebinding the allocator to the
container's value_type. Since GCC 8.1 that extension has been disabled
for C++11 and later when __STRICT_ANSI__ is defined (i.e. for
-std=c++11, -std=c++14, -std=c++17 and -std=c++2a).
Since the acceptance of P1463R1 into the C++2a draft an incorrect
allocator::value_type now requires a diagnostic. This patch implements
that by enabling the static_assert for -std=gnu++2a as well.
* doc/xml/manual/status_cxx2020.xml: Document P1463R1 status.
* include/bits/forward_list.h [__cplusplus > 201703]: Enable
allocator::value_type assertion for C++2a.
