Understood. Sorry for my lack of background on these platforms. Do you know if llvm.eh.selector and dwarf emission 
for a JIT execution environment works on your platform of choice? If so, and if the unwind system conforms to 
http://refspecs.freestandards.org/abi-eh-1.21.html, the port will not be too bad. Beyond use of fprintf and strtoul, and
an include of unwind.h, I don't believe there is much else that is specific to UNIX. These may even exist in your platform's
headers. The structures/APIs defined in unwind.h are fully defined and useable as is in
