+Subject: [PATCH] fix build w/newer glibc
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Building with newer glibc versions fails like so:
+bs_sg.c: In function ‘chk_sg_device’:
+bs_sg.c:354:6: error: implicit declaration of function ‘major’ [-Werror=implicit-function-declaration]
+  if (major(st.st_rdev) == SCSI_GENERIC_MAJOR)
+
+This is because glibc is dropping the implicit sys/sysmacros.h include
+from sys/types.h and making the few projects that need it include it
+explicitly.
