Ah, I did initially try this before emailing :-

gcc uapi-test.c -I ~/source/linux.git/include/uapi
In file included from /home/lrg/source/linux.git/include/uapi/sound/asound.h:26:0,
                  from uapi-test.c:2:
/home/lrg/source/linux.git/include/uapi/linux/types.h:9:2: warning: #warning

/home/lrg/source/linux.git/include/uapi/linux/stddef.h:1:28: fatal error: 
linux/compiler.h: No such file or directory

adding -D__EXPORTED_HEADERS__ to gcc command line gets rid of the warning, but 
it seems we are missing compiler.h (even in todays linux-next).

If this works for you, it may be an issue at my end.

Thanks
