If you move them, seems that it should be 'ext' not 'backward'.
However, I think promoting the allocator provided by that header to
the same status as __malloc_alloc_template and __new_alloc, etc

stl_pthread_alloc.h uses only those features provided by gthr.h thus
it could be rolled into stl_alloc.h while being de-pthreaded (thread
support would remain just be mapped through the abstraction layer
instead of directly using pthreads - in general as long as you don't
want to start a thread, anything simple pthread can do, gthr.h
supports with the same API).

We are of like mind.
