On my uclibc box (no libiconv)

root@localhost $ ls -al /usr/bin/iconv
-rwxr-xr-x    1 root     root         10878 Oct 19 19:22 /usr/bin/iconv

root@localhost $ ldd /usr/bin/iconv
        libc.so.0 => /lib/libc.so.0 (0x9ff12000)
        ld-uClibc.so.0 => /lib/ld-uClibc.so.0 (0x9ff75000)


I would really like to get some proxy developer to help me get uclibc
updated and also some patches to a few ebuilds (we hardly need any with
latest uclibc, at least on x86)

See here:
    https://bugs.gentoo.org/show_bug.cgi?id=308477#c21
...for some notes on building uclibc iconv *under* a uclibc build root
(needs some tweaking to help the build succeed - would like to see those
tweaks hit upstream, but ...).  The main snag is that you get iconv
*and* locale... I don't yet have a use for locale, but setting it to
build only en_gb.utf8 seems to work and I think total incremental
library install size was around 40-50KB

(I also noticed a plausible implementation of a functioning gettext
libintl.h ... ?)

Seems like uclibc has *near* correct working iconv and could do with
word getting out so it gets more exposure and hopefully soon a fully
working implementation..

Cheers
