I've also run in to this problem, though in my case I just fired up a VM
to work around it... I needed the VM anyway to actually run the
newly-built kernel. That said, it would be nice to be able to build on
the host and just scp the new vmlinuz across...
BTW, libelf.h has all the #defines, but it only #includes them if it
doesn't find an elf.h, which Cygwin has.
