Re: [gentoo-dev] Moving GCC-3.4 to stable on x86

[William Kenworthy <billk@iinet.net.au>]

As a user who has done this on a number of systems - its no sweat. 

Also, check some of the older guides for upgrading from gcc-2.95 to 3,
and 3.0 to 3.1 - should still be around somewhere.  Its been done
before, more than once - ask some of the older devs whove been around
since the early days(!).

Traps this time were uninstalling 3.3.6 without installing the
sys-libs/libstdc++-v3 first.  Ive put off removing 3.3.6 from the other
systems until I get the nerve up again.

So as well as instructions to do the task, some rescue for common
mistakes like this would be nice.
