Hello world,

the attached patch fixes a long-time regression where a c_funptr from a

The solution is a bit of a hack, but so is our whole implementation of

This is a further fix for P0634. When we have

we shouldn't assume that T::bar is a type because this isn't one of the

In this case, when a compound literal is in the parameter scope of a nested
function, current_function_decl is non-NULL, but we still don't want to

scope.

The __pool_resource::_M_unpooled member was declared with type
std::vector, which means that the type depends on whether debug mode is
active or not. Because the non-inline definitions in
src/c++17/memory_resource.cc are never compiled with debug mode, the
type declared in the header doesn't match
The nested typedefs in std::reference_wrapper are no longer present in
C++2a mode, so skip the tests that check for them.
The addition of the [[nodiscard]] attribute to a few functions causes
some failures in tests that intentionally ignore the return value.
Casting the result to void suppresses
These calls should have been qualified to avoid ADL anyway, but in C++2a
it becomes essential to qualify the calls in experimental::erase because
std::erase_if is also declared and the calls become ambiguous.

gcc's common configure script has a subtle flaw that it only tests
{init,fini.preinit}_array support when NOT cross compiling. This causes
cross builds to erroneously deduce that the feature is not supported by
the target.
