I can't reproduce it here with very similar setup. But I see your emerge --info shows you have gcc-4.2.3 selected instead of the gcc-4.3.2-r3 you mention. Could you try with gcc >= 4.3 (don't forget to gcc-config).
Yes, the 4.3.2 was a mistake; I have it in my system, but it wasn't enabled. It makes no difference, though: the build fails at the same point with either compiler. The included Hepevt.h file is exactly the same as the one installed on my system. Since sci-physics/root-5.22.00 isn't on portage anymore, I tried extracting and compiling the plain tarball; it compiles fine. The include/Hepevt.h on the work directort where the problem lies is identical to the one on my system from sci-physics/root-5.22.00.

A full emerge -e @system @world fixed it. Strangely, a simple emerge -e sci-physics/root sys-lang/gcc didn't do the trick, though, which seems very weird. Anyway, the bug was invalid all along.
