This is normal when building stage 1.  You should not see any warnings
when building stages 2 or 3.

The warnings occur mainly on gcc diagnostic functions.  The definitions
of the control sequences used in these functions change from time to
time.  This then triggers warnings when building stage 1 with an older
version of gcc.  These warnings are unimportant.
