Thanx for bringing some attention to my llvmdc project :)

I'll just jump in here and add that the llvm-gcc project is very mature and in most aspects at 
least as functional as the original gcc. All the backends however are not yet fully up to 
speed, but x86 is very well supported. There are some problems with exceptions on other targets 
afaik, but these are all being sorted out. The just-out LLVM 2.2 release is much closer than 
they've been before and I suspect 2.3 will put an end to most of the big issues.
