Hi,
this adds -Wshadow=local to the GCC build rules.
It is to be applied after all other patches in this series
including the trivial ones are applied.
Bootstrapped and reg-tested on x86_64-pc-linux-gnu.
Is it OK for trunk?
Thanks
Bernd.

* configure.ac (ACX_PROG_CXX_WARNING_OPTS): Use -Wextra instead of -W.
Add -Wshadow=local.
* configure: Regenerated.
