I just now updated a local gnulib tree and re-ran autogen.sh

Notice from module snippet/unused-parameter:

The gnulib.info documentation mentions "obsolete" in several
places, but it seems to be oriented toward gnulib hackers rather
than users.
My question is: What should i do w/ this module?
(a) Leave it alone -- "obsolete" is not "broken".
That's OK in the short term but in the long run I suggest using
_GL_UNUSED instead.
Related question: Where can i find info on how/why this module
became obsolete?
I used the shell command 'git log modules/snippet/unused-parameter',
which pointed me to commit d3837928885e91c9ddd465240b90a97aa342fda6

You're right that this is a bit obscure. The short version is: use
_GL_UNUSED instead of _GL_UNUSED_PARAMETER. You can see examples of how
to use _GL_UNUSED in Gnulib: it goes at the start of the parameter
declaration.
