The macros under the m4 directory are outdated a bit. When trying
to compile with newer gcc I see some errors:

This function changed its name due to the overwrite and ./configure
now yells an error, but it doesn't fail, so it's easy to miss.

apart from this particular file, which is specific for libvirt-related
projects, it's ok to sync the rest with gnulib, as it's being done on
regular (or rather irregular) basis.

So partial ACK for m4/manywarnings.m4 and m4/warnings.m4 only.
