And these warnings pop up for effectively every libMesh object build,
too - aren't they annoying?
The default MPI stack in Ubuntu has the same issues in its headers.
These warnings don't indicate any problem more serious than "those
developers didn't worry about checking and disabling gcc warnings",
but I ended up editing the file (commenting out the legitimately
unused parameter names in the declaration headers) so that any libMesh
and/or application warnings wouldn't be buried in noise.
