------- Comment #2 from rguenth at gcc dot gnu dot org 2007-12-10 09:55 ------- I think the problem described is that '-Wc++-compat' is used for building stage1 even if it is not available. Look at the output of configure in gcc/ and figure out which CC it is using for checking for the availability of -Wc++-compat.
