We want our end users to be able to rebuild all of Owl (including the
kernel) from source using only tools that are a part of Owl, yet we do
not want to be providing multiple versions of gcc (or of any other
package, for that matter).  We've been successful at not providing
multiple versions of development tools and libraries so far - keeping
the system small and clean, yet fully self-rebuildable.

I expect that we will fully move to Linux 2.6 before our next release,
but being able to move to gcc 4+ in Owl-current first simplifies our
development process.  (And, yes, we've got end users of Owl-current who
will be recompiling kernels.)

Also, I expect this kernel/gcc combination to receive quite some testing
soon, if/once it becomes supported.
