Comment 6 for bug 1310866

libc6-dev:
  Installed: 2.19-0ubuntu6.6

libc6-dev contains /usr/include/x86_64-linux-gnu/sys/types.h
types.h includes #include <bits/predefs.h> on line 323

When compiling things which contain #include <sys/types.h>, I get:
In file included from /usr/include/x86_64-linux-gnu/sys/types.h:25:0,
                 from scripts/basic/fixdep.c:106:
/usr/include/features.h:323:26: fatal error: bits/predefs.h: No such file or directory
 #include <bits/predefs.h>

There does seem to be some problem there.
