We try to achieve warning-free builds on glibc systems, because that
is the platform on which most developers look at the compilation logs,
and because with GCC we can enable useful warnings and disable less
useful warnings.

Warnings on other platforms catch our attention if they point to
potentially dangerous code. This is why I looked at your previous
report [1].

Having said that, if you want to fix this warning: Good patches are
welcome.
