+  # glibc 2.25 moved major()/minor() to <sys/sysmacros.h>.
+  # this commit should detect this: https://github.com/lxc/lxc/pull/1388/commits/af6824fce9c9536fbcabef8d5547f6c486f55fdf
+  # However autotools checks if mkdev is still defined in <sys/types.h> runs before
+  # checking if major()/minor() is defined there. The mkdev check succeeds with
+  # a warning and the check which should set MAJOR_IN_SYSMACROS is skipped.
