Works for me with gcc-4.1.1.  What is your `emerge --info` and did you try
recompiling everything it depends on with gcc-4.1?

my emerge --info ( I will try to emerge gcc-4.1.1 and test it again)

build with gcc-4.1.1

:( compiler switched to gcc-3.4. So my last report was wrong.
Error is still the same, even with gcc-4.1.1

-O3 seems to inline GuiHost<generalicon_c*>::chainiconstohost(generalicon_c*)
in gui.o
but that is also used outside, in building.cpp, so linker is not finding that.
Maybe a gcc bug.
Should we filter the -O3 then or wait for a fix to the compiler?

-O3 with gcc-4 replaced with -O2 in portage

You said you had the same error with gcc-3.4?

No, I don't. Problem I saw is with gcc-4.1 and gcc-4.1.1.
No problem with gcc-3.4.

So is this one fixed?  I'm a bit confused.

Bug is in the compiler, and my guess is that is still there.

Workaround for asc is to change -O3 with -O2 when using gcc-4. This change is
already in the ebuild.
So, yes, for what regards games team, it is fixed.

Let's mark it as such, then.

The reason why I left it open is as a remind for a bug for gcc that need to be
fixed.
I assigned this to Gentoo Toolchain Maintainers <toolchain@gentoo.org> for
exactly this reason.

However I don't insist on let it open, as it seems nobody care of that bug :)
