   4 Subject: [PATCH] mdadm.h: Undefine dprintf before redefining
   5
   6 dprintf is also defined in libc see
   7 usr/include/bits/stdio2.h, this comes into
   8 play especially when fortify sources is enabled
   9 and compilers like clang reports the override
  10
  11 In file included from policy.c:25:
  12 ./mdadm.h:1562:9: error: 'dprintf' macro redefined [-Werror,-Wmacro-redefined]
  13         ^
  14 /mnt/oe/openembedded-core/build/tmp-glibc/sysroots/qemux86/usr/include/bits/stdio2.h:145:12: note: previous definition is here
