The first stage uses the system compiler, which may have bugs or not handle special conversion type characters handled by the G= CC version being built (this particular warning). Therefore, warnings produced= by the system compiler are often wrong. Please, do not report them.=20 http://gcc.gnu.org/wiki/FAQ#stage1warnings It would be nice to NOT produce any warning during stage 1, but I guess peo= ple 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.
