Yeah, those are fine.

You could try building with "-polyvariance false" and/or with a
smaller inlining threshold, "-inline <n>".

I doubt the above will shrink stuff enough to fit into any of these.
But maybe 320.  The right solution is to get the Debian machines with
at least 512M.  Since a single 512M DIMM costs <$100, perhaps the
maintainers of these machines would be willing to upgrade them, if
they are made aware that the current situation causes problems.

Since you've made it to a stable point, go ahead and send it.
