GCC is built in stages. The first stage uses the system compiler, which may
have bugs or not handle special conversion type characters handled by the GCC
version being built (this particular warning). Therefore, warnings produced by
the system compiler are often wrong. Please, do not report them.

It would be nice to NOT produce any warning during stage 1, but I guess people
are happy enough just ignoring them to not bother sending a patch to fix the
build scripts. The build system of GCC is a huge complex mess, so one needs a
very good reason to play games with it.
