Yes, this would be painful in particular in cases like
master:advice.c:101: fprintf(stderr, _("%shint: %.*s%s\n"),
where we want to write more than just a variable-length buffer.
I am curious: is libintl (gettext) used on OpenIndiana? I ask because
AFAIR fprintf() is overridden in that case, and the bug might be a lot
easier to fix if it is in libintl rather than in libc.
Of course, it might *still* be a bug in libc by virtue of handing '%.*s'
through to libc's implementation.
Alban, can you test this with NO_GETTEXT?
Thanks,
Johannes
