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?
You don't need to downgrade. You can just emerge it alongside 4.5.3 and
switch to it with "gcc-config". You can switch back and forth at will,
meaning that you can build specific packages with 4.4.5 and keep the
rest of the packages on 4.5.3.
Or if you really want everything built with 4.4.5, you can switch to it
with "gcc-config" and then "emerge -e world".
