-New:
-- 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.
