FYI These changes may affect the testsuite and dejagnu, because they 
have code to prune warnings, and some of the sed patterns check for the 
string "warning".

dejagnu/lib/target.exp (prune_warnings) for instance has

    regsub -all "(^|\n)(cc1: warning: -mabi=32 does not support 
-g\[^\n\]*\n?)+\" $text "\\1" text
    regsub -all "(^|\n)(cc1plus: warning: -mabi=32 does not support 
-g\[^\n\]*\\n?)+" $text "\\1" text

These are already broken, because the warning text changed, but they are 
also doubly broken now because we emit note instead of warning.

Similarly, in gcc/testsuite/lib/prune.exp there are some sed patterns 
that check for warning.

It probably isn't worth fixing any of these unless someone runs into a 
problem.
