No, I am an AVR32 user, but I do not want the tree overloaded
with redundant patches.
You can build a toolchain using the external source.
The only difference is that you download the source 
*with* the patches from a different location, otherwise the build
process is identical.
If you need to fix something, you can apply patches.
The patches has to be located in target/device/Atmel/toolchain.

John requested that I put his prepatched toolchain source in the 
ATMEL_MIRROR and this was done within days after the
request, and it will not be hard to start supporting this
if someone is interested, and then the AVR32 toolchain
should have support for the latest version.
Again, if patches are needed for this, they can be added
to target/device/Atmel/toolchain tree.

Once I have time to test this, I will fix it, but unless
we have a rainy summer, I expect this to occur in August.

I know that there is complaints about not having write access
to the ATMEL_MIRROR. I do not need them to be at
this particular server, I prefer a server which will allow
access to more people.
Until we have a mirror with high bandwidth and high capacity
and accessible to all users with write access, I hope
we can live with this solution.  The cost will be a few days
of delay every time a completely new gcc version will
be available.

There was also complaints about speed, but I measured the download speed to several MBytes/s
so this must be temporary problems.

I have requested that the Atmel Trondheim provide official
prepatched source code of the toolset, but they think
that it is so close to have the toolchain support natively
that they think it is not worth the effort.
Hopefully they are right.

No objections to improvements, but you can do it without adding
the large patches.
