Adding support to load (map) ELF files to ntoskrnl is not a big problem 
I think (I have already done this and it should work)
Problems which I had was that normal ELF files do not contain an 
optional header which we need (it contains for example the required os 
and subsystem version and subsystem type) - this is what wingcc can be 
used for I think.
I have also had problems with building our libraries in ELF format to 
link some ELF test-app against, maybe this is easier with wingcc.

Maybe if I try again with the WINE tools I can get further... If anybody 
else wants to try I can send a patch for ELF support in ntoskrnl.
