svn commit: r184678 - head/sys/net

[Bjoern A. Zeeb]

Author: bz
Date: Wed Nov  5 11:37:26 2008
New Revision: 184678
URL: http://svn.freebsd.org/changeset/base/184678

Log:
  Do only define the variable if either INET or INET6 is defined.
  
  To prevent it from compiling without INET and INET6 we should put
  an explicit #error in there like we have in other files,
  but not rely on an unused variable.
