3 - switch to mt_allocator with --enable-threads=posix.
7 - global/extern allocator
11 - Policy-based design incorporating COW
12 vs. deep copy issues, MT scalability

14 "Generic<Programming>: A Policy-Based basic_string Implementation"
15 http://www.cuj.com/documents/s=7994/cujcexp1906alexandr/
17 - operator!= and utility/rel_ops operators need to be made safe with
18 string and vector iterator classes. basic_string::reverse_iterator may
19 be implemented incorrectly, or need things like
20 operator==(__normal_iterator, const char*&), and swap(vector)
22 - 'do the right thing' ctor fixing needs to be done for string. This
23 is still subject to some debate on the library issues list, so I
24 suggest punting till the dust clears.
26 - fix template members of basic_string<> to overload iterators and
27 non-iterators properly. (This is the infamous hack as in vector<> etc
32 - implement __convert_to_v and __convert_from_v without "C" library
33 functions and and LANG environment variable dependencies.
35 - use localedata to implement generic named (non-MT-safe) locales?
36 Figure out a way to use ICU data, like libjava? Re-package and use
37 the glibc localedata, even if we aren't on linux? Need a generic
38 locale model that does something besides the "C" locale.
40 - make locale::classic() separate from named locale code. This will
41 improve the static linkage situation, but will require new
42 initialization code. In particular, we need lazy-initialization of
43 locale::classic(), and maybe the has_facet/use_facet functions for all
44 the required facets. The end goal is a self-contained
45 locale_init.cc, or one with transitive closure without the locale
46 instantiations (locale-inst.cc) or the named locale bits
49 - Jerry(?)/Paolo(?) work on __float_to_char.
51 - minimize ctype convertion in data facets, see numpunct/num_put/num_get
53 std::basic_filebuf, 27_io
55 - wfilebuf, get variable-encoding working and tested, including
56 positioning and seeking. (I think this may be done now)
58 - wfilebuf testsuite (getting there...)
60 - look ahead for unbuffered io, so know when multiple putc's can be
63 - unlocked __basic_file + new mutext class
65 - optimized the sentries for istream/ostream
69 - add optimization hooks (esp. whitespace eating) to streambuf
70 - add _M_begin() and _M_end() to streambuf
71 - add algorithm specializations for [io]streambuf_iterator (copy find etc.)
75 - valgrind hooks into make check so can tell memory leakage
76 Some commentary on the valgrind users list
78 - add hooks for qmtest for visual diffs
80 - automatic testing of interactive tests
82 - diffing generated output files
84 - provide testsuites for numerics.
86 - make check-abi needs to have full symbol checking. Scope the LSB
87 testsuite, see what's going on with the typeinfo etc. bits.
89 - try to do a better job of ABI testing, with instantiations of all
90 standard-specified types checked, not just exported symbols.
94 - compression for wide versions of basic types, not just narrow
98 - create MT abstraction layer for atomicity to pthreads.
100 - solution for threads + C++.
102 - audit for places where __builtin_expect can be used.
104 - relocations, work on getting these down
106 - issues with __builtin_memcpy and std::copy from Jerry Quinn

111 - fix dependency tracking for includes (.h, .tcc) during build process.
113 - coordinate with "C" library people the "C" compatibility headers.
115 - Think about naming all member data and member functions consistently
117 funtions: _M_verb_adverb
118 data: _M_noun_adjective
120 - A C++STYLE guide that deals with nested namespaces, and that
121 everybody can live with.
123 - exception specifications need to be reviewed for all parts of the
124 library support and utility areas, particularly <new>. Part of this is
125 a standards issue, where the 27_io bugs/standard is really in an odd
128 - C-related issues WRT to io and filepos, mbstate_t. Seeking in wide
129 streams. May need to define operators for mbstate_t so that
130 'mbstate_t& == mbstate_t' is something that can be done.
132 - scoping/linking issues WRT to C structs need to be worked out. See
133 Nathan's commentary on cantrip, http://www.cantrip.org/cheaders.html
135 - auto_ptr: seems to be some disagreement on what is
136 standards-conformant behavior, specially on conversion operators.
138 - list::assignment operator needs const_cast
140 - a cleaner division between pointers-to-value_type and true iterators
141 needs to be drawn throughout the entire STL implementation.
143 - priority_queue conversions may be non-conformant
145 - Protect valarray::result_type (not Standard) and make it work with
146 the various helper classes.
148 - Make sure `valarray<bool> & == _Expr<_BinClos<logical_or,_ValArray,_ValArray,double,double>,bool>'
151 - All of the Library working group closed issues need to be
152 addressed. Some of them proposed resolutions are already in the v-3
153 sources, with macro-guards. Also, same with the TR.
155 - add deprecated features from Annex D
156 - add #ifdef wrappers for all of them, including in each
158 - replace typedef'd non-deprecated types with more type-safe equivalents.
160 - add feature-test macros for non-standard extensions
162 - add MT support for locale, string, istream, ostream
164 - need to think about doing a .texi or DocBook manual, instead of all
165 these HTML pages. In addition, it would be nice to have a full manual,
166 instead of a lot of ad-hoc pages. Weaknesses include numerics, locale,
169 - add FAQ entries -- improve the install instructions
173 - do more doxygen manpages
