...otherwise, at least with some --with-system-boost versions and C++11
compilers, like with Fedora's boost-1.50.0-4.fc18.x86_64 and
gcc-c++-4.7.2-8.fc18.x86_64, using this to copy-construct an instance of
boost::unordered::detail::ptr_node<std::pair<rtl::OUString,Bootstrap_Impl*>> in
the call to p_bootstrap_map->insert(...) in rtl_bootstrap_args_open
(sal/rtl/source/bootstrap.cxx) would memcopy the ptr_node and fail to call
rtl_uString_acquire, leading to memory corruption later on when
rtl_uString_release is called one time too often.
It is not entirely clear to me whether this is a shortcoming of the given Boost
version, but this patch solves the problem and brings rtl::Allocator::construct
in line with the (changed) Allocator requirements of C++11 anyway.
The problem potentially lurks with every use of rtl::Allocator, but only showed
now begining with LO 4.0 where

These are configuration files for various features as detected by configure.
Include only those files you need (in order to reduce rebuilds when a setting changes).
Settings here are only C/C++ #define directives, so they apply only to C/C++ source,
not to Makefiles.
Adding a new setting:
=====================
- do AC_DEFINE(HAVE_FOO) in configure.ac when a setting should be set
- choose the proper config_host/config_xxx.h file to use
- if it is a global setting (such as availability of a compiler feature),
use config_host/config_global.h
- otherwise check if there is a matching config_host/config_hxx.h file
- if none matches, add a new one:
- add config_host/config_xxx.h.in here, with just #ifndef include guard
- add AC_CONFIG_HEADERS([config_host/config_xxx.h]) next to the others
in configure.ac
- add config_hxx.h to config_host/.gitignore
- add #undef HAVE_FOO to the config_host/config_hxx.h , possibly with a comment
- add #include <config_xxx.h> before any #ifdef HAVE_XXX in a source file
