The ocaml bytecode interpreter on gcc runs 50% faster than the equivalent on
MSVC despite the fact that MSVC is generally optimizing better than gcc. The
reason? gcc supports computed gotos which apparently allows the interpreter
to translate opcodes to addresses of subroutines, thus avoiding an extra
computational step for each instruction.
