+Subject: [PATCH] build: Use AC_HEADER_MAJOR to find device macros
+
+Depending on the OS/libc, device macros are defined in different
+headers. This change ensures we include the right one.
+
+sys/types.h - BSD
+sys/mkdev.h - Sun
+sys/sysmacros.h - glibc (Linux)
+
+glibc currently pulls sys/sysmacros.h into sys/types.h, but this may
+change in a future release.
