How is this S/390 setup supported by GNU libtool? I'm sure it is since
many other packages use libtool, but I'm wondering whether special patches
would be required. We're planning on moving to that sometime.

Note that PostgreSQL also had a couple of bugs that violated standard C,
which are now mostly fixed. Perhaps that affects you. In any case you
perhaps want to look at the 7.1 development branch.

The path of least resistance is to name the template file after the
config.guess output. (I assume that you'll provide those guys with patches
as well.) Otherwise there's a file src/templates/.similar that matches
canonical host names to template files. (Yeah, we really shouldn't have
hidden files like that.)
