[Bug bootstrap/19818] New: [4.0 Regression] GCC 4.0 cannot bootstrap itself

["bonzini at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Warnings in libiberty and libcpp prevent GCC 4.0 from bootstrapping itself,
because libcpp's configure uses -Werror.

The easiest way to reproduce this is to configure GCC 4.0 with
--enable-bootstrap so that libcpp is bootstrapped as well.

Severity is normal and not critical because releases do not use -Werror, but the
bug ought to be fixed before GCC branches.
