[sorry you're getting this twice, Jeff; I hit "reply" instead of "reply to all", der...] Installing gmp and mpfr libraries on your build host should do it. They only need to be linked in to the compiler for it to be able to do constant folding reliably at compile time - you don't have to go and fetch their source and cross-compile it for the target. Is this any different from needing a working native compiler, Unix tools, math library and ofher bits that you already need to be able to build the other versions? At most we could put a special thing into CT to check for extra build dependencies if you're building gcc-4.3, but it seems from the message that the configure script already does this and reports extensively, so why bother?
