Subject: [PATCH] include sys/sysmacros.h for major/minor

These functions are not part of any official spec, and glibc has always

kept them in sys/sysmacros.h.  As glibc moves to conform to POSIX, and

more alternative C libraries come up, we need to include this header

explicitly to get the prototypes.  Otherwise we fail to build like:

affinity.c: In function 'affinity_file':

affinity.c:177:7: warning: implicit declaration of function 'major' [-Wimplicit-function-declaration]

   if (major(d) != maj || minor(d) != min)

       ^

affinity.c:177:26: warning: implicit declaration of function 'minor' [-Wimplicit-function-declaration]

   if (major(d) != maj || minor(d) != min)

                          ^

./.libs/libnuma.so: undefined reference to 'minor'

./.libs/libnuma.so: undefined reference to 'major'

collect2: error: ld returned 1 exit status
