>Environment:   


>Description:
The kernel is built with multicast routing support, even when the config
option MROUTING is not supplied.  This adds useless bulk to the kernel for
users who have no use for multicast routing.


>How-To-Repeat:
Build a kernel without the MROUTING option, and look at the size of the file
arch/<platform>/compile/<name>/ip_mroute.o.  Now apply the patch provided
below, build a kernel with the MROUTING option, and look again.


>Fix:
The problem results from the removal of some conditionals in the file
netinet/ip_mroute.c.  The fix is to restore these conditionals.  The
following patch does this.
