This allows us to add features to freestanding which allow specifying non-default allocators (generators, collections, ...) without having to modify them.
libstdc++-v3/ChangeLog: * include/bits/memoryfwd.h: Remove HOSTED check around allocator and its specializations. --- Evening, This patch adds std::allocator as a declaration to freestanding, so that it doesn't block various other bits of the library (such as collections or the generators that I intend to send in soon) from being added to freestanding anymore. I don't intend to pull in anything but <generator> into freestanding in this release, though, so, this patch will have little impact for now. Testing on x86_64-pc-linux-gnu (the tests are not done yet, but I see no relevant fails in previous test runs). The follow-up patch also marks a new test as freestanding (as it was failing). OK for trunk?
