FYI, the build has now (just about) completed, so the full impact of
gcc 4.1 is becoming clear. About 750 ports failed to build out of
12246 attempted, and those failures prevented the building of about
2600 ports in total. Most of these extras are caused by the failure
of a few high-profile ports (accounting for this there are indeed
probably about ~1000 failures tree-wide).
Among the major causes of this "collateral damage" are:
some parts of gnome
To repeat, the gcc 4.1 import is not immanent but will happen on a
timescale of a month or two. Anyone who wants to get a head start on
the problems shown by the package build will ease the lives of current
users later down the road :)
