+Subject: [PATCH] usbmon: include sys/sysmacros.h for makedev func
+
+Since glibc has always placed these funcs in sys/sysmacros.h, and other
+C libs require this, include it directly.  Otherwise we fail to build:
+usbmon.c: In function 'make_device':
+usbmon.c:966:8: warning: implicit declaration of function 'makedev' [-Wimplicit-function-declaration]
+  dev = makedev(major, p->ifnum);
+        ^
+usbmon.c:966:2: warning: nested extern declaration of 'makedev' [-Wnested-externs]
+  dev = makedev(major, p->ifnum);
+  ^
+...
+usbmon.o: In function 'make_device':
+usbmon.c:966: undefined reference to 'makedev'
