Should be standards compliant and with several optional features,
including support for hexadecimal float notation, locale awareness,
glibc-like locale-specific digit grouping with the `'' flag, and
positional arg support. I tested it pretty well (finding several
bugs in glibc's scanf in the process), but it is brand new so be
aware.
The *wprintf functions now support floating point output. Also, a
couple of bugs were squashed. Finally, %a/%A conversions are
now implemented.
Implement the glibc xlocale interface for thread-specific locale
support. Also add the various *_l(args, locale_t loc_arg) funcs.
NOTE!!! setlocale() is NOT threadsafe! NOTE!!!
The strto{floating point} conversion functions are now locale aware.
The also now support hexadecimal floating point notation.
Add the wcsto{floating point} conversion functions.
Fix a bug in mktime() related to dst. Note that unlike glibc's mktime,
uClibc's version always normalizes the struct tm before attempting
to determine the correct dst setting if tm_isdst == -1 on entry.
Add a stub version of the libintl functions. (untested)
Fixed a known memory leak in setlocale() related to the collation data.
Add lots of new config options (which Erik agreed to sort out :-),
including finally exposing some of the stripped down stdio configs.
Be careful with those though, as they haven't been tested in a
long time.
(temporary) GOTCHAs...
The ctype functions are currently incorrect for 8-bit locales. They
will be fixed shortly.
The ctype functions are now table-based, resulting in larger staticly
linked binaries. I'll be adding an option to use the old approach
in the stub locale configuration.

LC_TIME, LC_MONETARY, and LC_MESSAGES for the SUSv3 items. Also,
nl_langinfo() when real locale support is enabled.
New implementation of ctype.h.
New implementation of wctype.h.
New implementation of most of the string functions (smaller).
New implementation of the wcs/wmem functions. These are untested, but
they're also just preprocessor-modified versions ot the corresponding
str/mem functions.
Tweaked qsort and new bsearch.
Stuff still pending:
stdlib.h and wchar.h mb<->wc functions. I actually have working
versions of the stdlib ones, but the reentrant versions from
wchar.h require some reworking.
Basic replacement and translit support for wc->mb conversions.
(groundwork laid).
Simple-minded collate support such as was provided by the previous
locale implementation. (mostly done -- 8-bit codesets only)
Shared mmaping of the locale data and strerror message text.

it and that I could see needed it.
Should be pretty low impact as these are only defined when using C++.

I started trying to read the glibc code -- but that code is far too
messy to be read. So I just wrote a silly C app against glibc, set
the locale to POSIX, then called localeconv(). I wrote this version
of localeconv.c so it returns the same stuff.
