Hi Jonathan,
> The SSO basic_string has a non-standard insert(iterator, initializer_list)
> overload, from a C++0x draft. This adds the correct overload, while also
> preserving the old one so that the old symbol is still exported from the
> library.
>
> The COW basic_string doesn't have any of the C++11 changes to the insert
> overloads (they all still have non-const iterator parameters and the
> ones that should return an iterator still return void). This doesn't
> make any change to the COW string.

it seems a couple of pattners are a bit too tight now in gnu.ver: this
caused a couple of failures on 32-bit Solaris and subsequent tests
failing to link due to symbols now hidden:
