The problem is that you probably do not have the *correct* host environment to be compatible with, yet. You do need to compile the host headers with the host-specific macros defined and that will make some of the code in them uncompileable for NVPTX (e.g due to inline asm or unavailable builtins). Nor do we have the long-term solution for the "compatible, somehow" part, as we're replacing part of the host headers, implementation of which we do not control. We can drop the 'temporary' part, but I think the story here is far from over, so a prominent TODO is needed.
