   3 Subject: [PATCH] batctl: suppress implicit-fallthrough compiler warning
   4
   5 GCC 7.1.0 complains about an intended fallthrough.
   6 “__attribute__ ((fallthrough))” in this part of code would suppress this
   7 warning. Because older GCC compiler don’t understand this statement attribute
   8 and because there is already a comment in the source containing
   9 “falls?[ \t-]*thr(ough|u)” we can suppress the warning with the
  10 “-Wimplicit-fallthrough=2” warning option. Unintended fallthroughs without a
  11 comment would trigger this warning again.
  12
  13 To avoid compiler recognition in the Makefile a simply change of the comment
  14 is sufficient to suppress the warning. For some reason only stand alone
  15 comments mentioned in [1] are recognized so the comment has to be split up into
  16 two parts.
