Dan,
MIPS patches are always welcome, even if, as you said, NPTL branch
merge is stalled again... mea culpa, but I'm fully busy in other
kernel activities at my company.

which piece is old... if you are referring to the NPTL code itself,
you are right.
I would also like to get an

unfortunately stalled, even if we (@ST) have ported argp and FTS
support in uclibc to support libdw (from elfutils).
We are planning to post patch asap.

Cheers,
Carmelo
