Just re-emerge the older version e.g. emerge =...gcc-4.4.5 (... is the

version.

It's better to emerge it by using its slot:

  emerge gcc:4.4

so you can get updates normally for that slot.

    Hi,

    I want to downgrade gcc from 4.5.3-r1 to 4.4.5.

    The Gentoo gcc UPgrade guide tells me, that ABI are only upward
    compatible which implies problems when downgrading and not upgrading.

    Nonetheless a downgrade is needed here and I want to go
    to gcc-4.4.5.

    How can I acchieve this in a clean way?

    Best regards,
