sys-devel/binutils

      Latest version installed: 2.16.91.0.1

I'm not sure if it's still hard-masked or if it is now ~arch, but it was
hard-masked when I overlayed and keyworded it, as it was a dependency of
the (also still hardmasked) gcc-4.x.  That's what I met when I said
"related" binutils -- I had to unmask both (tho I had a choice of possible
binutils versions to unmask and merge) to get gcc4.

The beta2 thing wasn't major.  It was xmms-kde, a kicker applet to control
xmms/noatun/xmpeg.  It would launch sometimes, but not others, complaining
about a library it couldn't find.  Actually, now that I think about it,
the problem and why it now works was probably that I needed to run
fix_libtool_files.sh, and did so after the -rc1 merge died shortly after
initial run.  After running fix_libtool_files.sh, the merge finished. 
xmms-kde probably had a dependency on something configured with an la file
that pointed to a stale gcc version, so running the script fixed it as
well.

Well, the major problem, is libstdc++.  The gcc-4.0 versions are supposed
to be generally backward compatible with the 3.4 versions, and I've found
it to be generally so.  There are occasional issues, but they are usually
fixable if one can find the correct combination of 3.4 and 4.0 compiled
applications and libraries.  Running fix_libtool_files.sh and recompiling
the target application often helps, as was apparently the case with
xmms-kde, but to do that, you have to know which specific version is
causing the error, so you can run it against that version.  This of course
isn't a big issue with binary distributions where everything in a release
is compiled using the same gcc, thus against the same libstdc++.

You are correct, however, it can be "annoying", at times.

FWIW, I'm now running a gcc-3.4.4 compiled kmail, and no problems yet, but
I've only had a few spams come thru since I restarted it, so I can't say
the problem's definitely fixed.  So far tho, so good (said the guys
jumping out of the twin towers as they passed the 10th floor, hopefully
this experience ends rather better, and hopefully noone finds this in
/too/ bad a taste).
