[gentoo-user] gcc-3.3.6 and the pentium-m flag

I am trying to install virtualbox to play with it (any other non-masked
virtualization tools besides Xen and qemu that you might recommend me
trying out?) and it wants to pull in gcc-3.3.6.  That's fine, but I am
using the -march=pentium-m flag on my laptop and that wasn't a valid
flag in the days of gcc-3.3.6 so the build fails.  Is there something
similar to /etc/portage/package.use where I can specify different CFLAGS
for this particular ebuild?  Other suggestions?

Either put something like the following in /etc/portage/bashrc:

case "$CATEGORY/$PN" in
    app-emulation/virtualbox)
        CFLAGS="-march=..."
        CXXFLAGS="$CFLAGS"
    ;;
esac

Or:

# mkdir -p /etc/portage/env/app-emulation && echo 'CFLAGS="-march=..."
CXXFLAGS="$CFLAGS"' > /etc/portage/env/app-emulation/virtualbox

[2 good sugestions]

Hah, I just assumed it was one of those few packages (like qemu-softmmu) that 
actually needed to be compiled with gcc-3.x. But indeed according to the 
ebuilds it's just need the right ABI for libstdc++. ;)
