Really? I've not been designing compilers for a dozen years now, but I
haven't seen any evidence that it has really gotten particularly easier. And
it certainly wasn't cheap back then, and the result was not even "somewhat
optimizing". Retargetable compilers fit very closely to the UNCOL myth our
moderator just exposed.
