GCC 4.5 unmasking and etc.
I was hoping to get GCC 4.5 unmasked much sooner than this, but I somehow got wrangled into running the field end of a big survey project at work and as a result I've been pretty much living out of a motel since mid-August. The good news is that thanks to the efforts of many very helpful people who aren't me, the last major packages that needed fixing are taken care of and we're finally ready to drop 4.5.1 into ~arch this weekend.
This is a major update so you may want to review our upgrade guide:

A rundown of the new features in this release can be found in the upstream release notes:
http://gcc.gnu.org/gcc-4.5/changes.html
LWN ran an article highlighting some of the changes as well:

We will not be supporting Link-Time Optimization (LTO). It's there if you want to use it. Using it will most likely break your system. Graphite is supported in the sense that we won't automatically close bugs as INVALID as we did with 4.4. But we probably won't be spending a lot of time on them.
Bug #296658 tracks the remaining packages that are broken with GCC 4.5. You can also see the full list.
