The __gnu_debug string (mostly) implements the C++11 API, but when it
wraps the old COW string many of the member functions in the base class
have the wrong parameter types or return types. This makes the
__gnu_debug::string type adapt itself to the base class API. This
actually makes the debug string slightly more conforming than the
underlying string type when using the old ABI.
* include/bits/basic_string.h [_GLIBCXX_USE_CXX11_ABI]
(basic_string::__const_iterator): Change access to protected.
[!_GLIBCXX_USE_CXX11_ABI] (basic_string::__const_iterator): Define
as typedef for iterator.
* include/debug/string (__const_iterator): Use typedef from base.
(insert(const_iterator, _CharT))
(replace(const_iterator, const_iterator, const basic_string&))
(replace(const_iterator, const_iterator, const _CharT*, size_type))
(replace(const_iterator, const_iterator, const CharT*))
(replace(const_iterator, const_iterator, size_type, _CharT))
(replace(const_iterator, const_iterator, _InputIter, _InputIter))
(replace(const_iterator, const_iterator, initializer_list<_CharT>)):
Change const_iterator parameters to __const_iterator.
(insert(iterator, size_type, _CharT)): Add C++98 overload.
(insert(const_iterator, _InputIterator, _InputIterator)): Change
const_iterator parameter to __const_iterator.
[!_GLIBCXX_USE_CXX11_ABI]: Add workaround for incorrect return type
of base's member function.
(insert(const_iterator, size_type, _CharT)) [!_GLIBCXX_USE_CXX11_ABI]:
Likewise.
(insert(const_iterator, initializer_list<_CharT>))
[!_GLIBCXX_USE_CXX11_ABI]: Likewise.
* testsuite/21_strings/basic_string/init-list.cc: Remove effective
target directive.
