Could you summarize the failures/issues that you found with this kind of 
approach?
We'll have to do sth similar eventually, and up to now I excepted that 
customizing the compiler/linker should work most of the time. Perhaps with the 
help of a custom-written linker-wrapper (using llvmc).

It would be great if you could share howto's / Makefile patches / ... once you 
can build some of these large applications with the LLVM tools.

Thanks,
Torvald
