"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."
