That part about "native" -- yeah, it's there. The existence predicate
returns true. IT'S SOMETHING THAT IS EASILY SKIPPED OVER WHEN SKIMMING
THE DOCUMENT BECAUSE, HECK, THE GCC3 DRIVER COMPILES DIRECTLY TO
BYTECODE SO WHY DOESNT GCC4?

It's a "least surprise" issue. If gcc3 produces bytecode directly, why
did the gcc4 driver create such a large departure from original,
expected functionality? It's a rhetorical question, BTW.
