Subject: [PATCH] Fix build with --disable-ipv6
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Otherwise build breaks with:

fping.c:399:14: error: ‘ident6’ undeclared (first use in this function); did you mean ‘ident4’?
  399 |     ident4 = ident6 = getpid() & 0xFFFF;
      |              ^~~~~~
      |              ident4
