[Bug other/36368] New: Fixincludes corrupts sysmacros.h

Compiling this program:

#include <sys/types.h>

$ gcc a.c

Here is the relevant part of diff -u /usr/include/sys/sysmacros.h
.../include-fixed/sys/sysmacros.h

 # if defined __GNUC__ && __GNUC__ >= 2
-__extension__ extern __inline unsigned int
-__NTH (gnu_dev_major (unsigned long long int __dev))
+__extension__ extern __inline __attribute__ ((__gnu_inline__)) unsigned int
+gnu_dev_major (unsigned long long int __dev) __THROW
 {
   return ((__dev >> 8) & 0xfff) | ((unsigned int) (__dev >> 32) & ~0xfff);
 }

Note that __THROW expands to __attribute__ ((__nothrow__)) when compiling in C.
But it seems this attribute isn't allowed on function definitions.
