[Gerald Pfeifer]

Walter,

I am happy to announce your appointment as maintainer for this port / 
these ports pending initial technical approval.  That could come from
Richard or Joseph, for example.

As part of your initial commit, please add your name to MAINTAINERS
and submit a news item for our main page as well as an entry for the
GCC 4.7 (or 4.8) release notes at htdocs/gcc-4.7/changes.html (cf.
http://gcc.gnu.org/cvs.html ).

Happy hacking!

Gerald
