Oops, overlooked these two.
But libgcj-bc is uninteresting as it does not show up in the
dependencies of any other of the listed packages ...
libgcj-common is an interesting candidate for adding the Breaks, as it
is included in all the upgrade paths. Unfortunately there are still a
few failing upgrades, because squeeze's apt decides to keep the old
versions of gcc-4.4-base and libgcj-common instead of kicking out
gcj-4.4-base (and some old libs that depend on this).
I've tested both squeeze2sid and squeeze2wheezy, both had the same problems.
So the solution with updating gcc-4.7-base works better because it is a
new package, so during the distupgrade apt only has two choices
(install or keep uninstalled) and "keep uninstalled" means a lot of
packages cannot be upgraded. While for an updated (with additional breaks)
gcc-4.4-base or libgcj-common which already exist in squeeze, apt actually
has three choices: upgrade, keep old version or remove. And keeping a few
old packages may weigh less expensive than removing a small dependency
tree of obsolete packages (gcj-4.4 and libs and support and ...)
