[please note this is lucid+1 material, not targeted for lucid, but you're 
welcome to fix things already for lucid]

A rebuild test of the current Debian unstable distribution on x86_64-linux-gnu 
was done, one rebuild test with the current gcc-4.4 from the branch, and another 
one with GCC trunk 20100107. The latter did show about 200 additional build 
failures, which are listed in [1] (minus some already known failures due to 
misconfiguration for the rebuild with gcc-4.5). The GCC test packages used for 
the test rebuild are available for i386 and amd64 at [2].

Lucas did do the test rebuild and a quick analysis of the results, repeated here:

  - some symbols problems (sqlxx, strigi)
  - tests failure (incorrect code generation?)
  - many new gcc errors (compiler becoming stricter, as usual?)
  - some ICEs
  - several builds where g++ hanged (e.g fwbuilder, but there are others).
    the timeout for the builds was set to 60min.

I'll go through the list of build failures this week, trying to file appropriate 
bug reports for GCC or the distribution. If you do want to help with this work, 
please update the wiki page before you start working on a package.
