This is the tenth snapshot of the libstdc++ rewrite. It is still
incomplet and incorrekt. It's a lot less incomplete and incorrect than
some of the earlier snapshots though, and quite usable.

The Standard C++ Library v3, or libstdc++-2.9x, follows an open
development model, attempting to be fully buzzword, bazaar, and GNU
compliant. Full details on participating, including contributor
guidelines, mailing list subscription, mailing list archives,

found at the following URL:

New:
---
- MT safe string. Supported CPUs are alpha, powerpc, x86, sparc32 and sparc64.
- Configure support for --enable-threads=posix, as well as initial IO
locking implementation.
- Support for native building on Solaris 2.5.1, Solaris 2.6, Solaris
2.7, cygwin, [alpha, powerpc, x86]-linux, and preliminary support for
Irix and Aix4.2, Aix 4.3 hosts.
- --enable-namespaces is on by default.
- Configure and Makefile support for "drop-in" replacement to
libstdc++-v2 completed. It is now possible to bootstrap g++, and
have g++ find libstdc++-v3 headers and libraries by default.
- Synched with CVS egcs libio.
- Cygwin native compiling supported.
- Cross compiling and embedded targets (newlib) with multilibs support added.
- SGI's strstream implementation has been added.
- Copyright on all sources assigned to the FSF.
- Configure, build and install documentation has been added.
- Support to enable long long has been added.
- More valarray improvements.
- Extractors and inserters for std::complex have been added.
- Extractors and inserters for void* have been fixed.
- autoconf macros are now in _GLIBCPP_ namespace.
- group checking for num_get implemented.
- namespace std:: is now on by default.
- choice of "C" include strategies, including the shadow header work,
or generic global to std mapping of required "C" types.
- cpu/atomicity.h tweaks, additions of ia64 and arm support.
- abstraction of atomicity.h header to support notion of os/atomicity.h files.
- addition of backward header bits
- use of system_header pragma
- Conditional use of -Werror
- preliminary support for new g++ diagnostics capabilities, including
-fdiagnostics-show-location=once
- pedantic and shadow argument warning fixes
- Ugly, yet correct mechanism for dealing with "C" math adopted,
including the use of builtins.
- updates and configure/build work to support new libtool
- addition of strstream
- valarray work
- complex work
- update to SGI STL 3.3
- libio sync between glibc/libstdc++-v3. Some divergence since initial
merge, but sources remain quite close.
- IO fixes for alpha
- wide character work for IO when using libio
- addition of c_io_stdio and "C" IO abstraction layer.
- auto_ptr fixes, testsuite additions
- Attempts to use -ffunction-sections -fdata-sections and
--gc-sections, depending on use of GNU ld and specific features. As of
late, --gc-sections has been disabled due to problems with it throwing
away initialization sections. This work is ongoing.
- long double support
- sub directory removal, coherent organization of cpu and os-specific
files, consolidation of include directories, integration of the C++
support bits for operator new/delete,exceptions, etc. All includes
are now either in the include/* hierarchy or in libsupc++'s sub directory.
- Support for more platforms, including irix and bsd variants.
- filebuf tweaks to deal with variable-size buffers.
- filebuf implementation for putbackc, etc. al.
- ctype rewritten. Includes ctype<char>, ctype<wchar_t>, and others.
- codecvt rewritten. Includes codecvt<char, char, mbstate_t>,
codecvt<wchar_t, char, mbstate_t>. In addition,
implementation-defined conversions using iconv are now supported with
the __enc_traits partial-specialization of the State template
parameter of the codecvt class. In this manner, conversions between
encodings such as UCS4, USC2, UNICODE, UNICODEBIG, UNICODELITTLE, etc
can be performed.
- preliminary work on named locales
- preliminary documentation for locale implementation has been established.
- Many, many bug fixes.
- Many, many testsuite additions and consistent VERIFY usage.
- work on mkcheck to make it more flexible, use libtool, etc.

Development tools:
------------------
You will need a recent version of gcc to compile the snapshot of
libstdc++. The recently released gcc-2.95.2 works well. In addition,
libstdc++. The use of CVS g++ is strongly recommended. In addition,
you may need up-to-date tools for modifying Makefiles and regenerating
configure scripts: automake (version 1.4 from Cygnus, not the one on
the net) and autoconf (version 2.13 and higher). Please see the
website for more info on where to obtain these additional tools.
If you compile programs -fnew-abi -fno-honor-std, uses of RTTI and
certain other language features will link only if you build your
compiler's libgcc using the same flags. (The defaults use the old
abi.) Using -fnew-abi offers real benefits, but note that it is not
stable: later snapshots will *not* be binary-compatible with code
compiled with older snapshots. See the configuration options page in
the Documentation section.
configure scripts: automake (version 1.4), autoconf (version 2.13 and
higher), and libtool.

<P>Note 2: All solaris toolchains were configured with --with-gnu-ld
--with-gnu-as --with-gnu-binutils --with-gcc. (That's a lot of --with's...)

<P>Note 3: Configuration and initial support for AIX has been
completed. However, problems with the compiler/linker have
prevented testing. For instance, mknumeric_limits will fail unless
weak linking is possible, which doesn't seem possible on
AIX. The initial bug report is

I opposed the original solution (involving weak symbols) on ELF, as
it seemed to be the wrong idea. I'm not sure what the right fix is,
and don't think I have time to work on it right now.
