Can you retry with SVN r43118 and newer?

Apparently, as usual with BSDs, they sometimes break their libc naming
compatibility, which is a problem as we link against it, but we don't use
their C headers obviously. They renamed the reference to
__setlocal_mb_len_max_32 to __setlocale50 in NetBSD 6, which shipped in
2012... I changed it now in our trunk, but this means NetBSD releases
earlier than 6 won't be supported. As NetBSD 5 EoL'd in 2014, I don't see
this as a problem, necessarily.

BTW, as a testcase, you could build a test-app which uses widestrings and
links against libc. It doesn't have to be a GUI app to reporduce this
issue.
