Yes, I know. I'm actually basing my project on a modified click build 
system (great work BTW). But my question is _why_ does no support? Too 
difficult? Impossible? You don't need no stinkin' exceptions :) ?

Yes, I found that one too. Although their web site is down, I found 
MOOL, whith is based on that codebase. Unfortunately, it is based on a 
very old gcc and very old kernel. What I'm shooting for is 2.6.28+ and 
gcc 4.3+ with dwarf2 EH. I've made some progress, but now I'm stuck on 
stack unwinding, so I really need to know if this is possible at all 
without major modifications to the kernel itself. I'de really appreciate 
any kind of info on the matter. Thanks.

cheers,
