Subject: Fix build with --disable-ipv6
X-Git-Tag: v4.4~3
X-Git-Url: https://git.gsnw.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9ef7da8c5c73645c45487fd8ca815b047d85cba1;p=fping.git

Fix build with --disable-ipv6

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
