Sorry for being unclear.  Someone is using __ASSEMBLER__ to inhibit type
definitions in kernel headers.  There is a literal “#define
__ASSEMBLER__ 1” in the source code.  I assume this is to get access to
kernel header constants while avoid conflicts with glibc headers.

This is not about an .S file include <sys/stat.h>; it's fairly obvious
that this wouldn't make sense.

Thanks,
