perl has a native compiler, it just doesn't work for 5.10 and blead yet. I'm working on it in my rare spare time, but now it's winter time and I was motivated by a company which needs it.
The new cygwin gcc-4.3 has obviously still some bugs, because the B::Bytecode compiler suddenly smashes the stack, but on other platforms it still works okay.
I'm working on B::C right now.
version 1.04_21 fixed regexp (strange and hard).
Today I got xpvmg working (easy),
PADLISTs are very broken with DEBUGGING only (strange and hard),
and some more minor issues are missing.
I hope to get it ready end of february. I also have to keep an eye on my broken compiler on my main platform.
