One reason I asked was because you'd have to force LC_ALL=C to make that
work, unless you want to check for every translation of the warning.

Another, as said earlier already, is that the warning is given for valid
code too sometimes, but as long as it's possible to state in the ebuild
that the warnings are safe to ignore for that package, I guess that's
okay.
