gcc 4.7 support

I am now (finally) building Trinity in a gcc 4.7 environment. So far pretty good news. I can't build tdebindings with xparts and tdegraphics. Otherwise I seem to be moving forward. As I build each package I notice what fails and then head to the bug tracker looking for patches. Bug report 958 is a first start but there are a few other bug reports too. If you have not submitted any related gcc 4.7 patches, please do so. As an attachment here in the list is fine or a bug report. I have tested some of the patches and they work for me as well. Therefore I am going to start pushing those that I test successfully. (Working for two or more people using different distros is a reasonable litmus test.) I mention this here as a friendly warning. :-) That is, if you are building from GIT, please check all resources before posting to the list. That includes doing a git pull to discover whether I pushed a patch. I'm even learning. :-) I just created a tdepim patch that needed a this-> pointer. Thanks to all of you who have created similar patches, from which I learned what to do. I don't grasp the whole "this" pointer concept, but I can patch. :-) Darrell
