I don't want to see stuff like this for every non-trivial file I compile
(that's Fedora Core 6, not some ancient distro):

/usr/include/sys/socket.h:88:62: error: attribute
'__transparent_union__': ignoring attribute __transparent_union__
/usr/include/sys/socket.h:92:68: error: attribute
'__transparent_union__': ignoring attribute __transparent_union__
/usr/include/netdb.h:661:60: error: typename in expression
/usr/include/stdlib.h:72:56: error: attribute '__transparent_union__':
ignoring attribute __transparent_union__
/usr/include/regex.h:543:27: error: typename in expression

I'm not going to fix socket.h.  I'm checking my code, not glibc.

Actually, the kernel should not be affected since it's compiled without
system includes.
