[ Note that GCC-4.6 will not be used for natty / 11.04, but
we consider using this version for the O-series / 11.10 ]
A test rebuild of natty/main using the current GCC version from the trunk was
finished last week. While only one internal compiler error was found, some more
build failures were seen due to new warnings and more strict frontends. A list
of build failure can be seen at
http://people.ubuntuwire.org/~wgrant/rebuild-ftbfs-test/test-rebuild-20110111-gcc-natty.html
If a package appears in the `superseded' section, it doesn't mean that the build
failure with GCC-4.6 is fixed.
Some comments and hints for fixes can be found at
https://wiki.ubuntu.com/GCC4.6
Please extend the wiki page if appropriate.
To work on the build failures, please use either the gcc-snapshot package from
natty or the gcc-4.6 package from the ubuntu-toolchain-r/test PPA.
A large number of build failures is seen for packages building with -Werror. The
compiler packages above were changed to add a -Wno-error=unused-but-set-variable
when -Werror is found. Despite this local change the these packages need to
build without this local change.

PS: Fixing build failures with GCC-4.5 in natty should still have priority ;)
