Tracking GCC 4.4 related build errors

I started building the Debian archive with GCC 4.4 ten days ago to report build errors. I've completed the archive build now and reported about 220 bugs (the majority with patches). There are roughly 30 build failures left that I haven't analyzed yet. There are also about 35 packages that fail because the boost headers don't work with GCC 4.4. I'll try to build them when the boost headers get fixed.

The majority of GCC 4.4 build errors are trivial. The large majority of failures is because of missing #include statements. There are also about 20 build errors because of improved preprocessor checks.

I'll try to do another archive build when the gcc-4.4 package is in Debian.
