I have just updated to the latest svn revision, and it seems you forgot to #include cpplib.h and langhooks.h.
Note about the c-family issue, you will be allowed to apply it (in the trunk, and then in the melt branch) in 24 hours unless the plugin maintainer block this one. I can't do it by myself as i don't have write access to the svn repo. See Joseph S. Myers post at http://old.nabble.com/-PLUGIN--c-family-files-installation-td32038394.html Romain Geissler
