I did some double-checking, and it turns out that for gnat alone our 
build system uses Gentoo's gnatboot-4.1 instead of gcc 4.5.1. Building 
using gcc 4.5.1 was successful, so either the GCC install docs are 
incorrect in saying that the gnat version must be 4.0 or later, or there 
is some oddity in how Gentoo built their gnat.
