Fine, but we don't need a Gnulib module for every POSIX API, even if the
API is not obsolete. Particularly an API like ffs, which is present only
because stdbit.h didn't exist way back when. And r

Hi,
Now that we have stdbit.h I think that it would be nice to reduce the
duplication in all the bit operation modules.
Is there any reason not to use stdbit.h for ffs, ffsl, ffsll,
count-leading-zeros, count-one-bits, count-trailing-zeros?
I've attached an unpushed patch for count-one-bits and
