That's certainly nice to hear, considering the number of changes required were
considerably less than what was needed for gcc-4.4 (then again, many of them were
backports from gcc-4.5 anyway ;). Of those changes made, they all turned out to be
pretty quick/lazy edits.

Just preparing an update for 4.5.2 (and a strange segfault when building D2).
After that will begin the usual dstress/testsuite run against it to get an idea of
just how production ready it is.
