> Hi, when building gcc I get bunch of build warnings like these:
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.
