I changed the defconfig in arch/um to include CONFIG_IP_MROUTE and that set it up correctly...

Much thanks to all...

Now I have another question:

I patched linux-2.4.28 with the uml patch 2.4.27-1, did the configs, make, etc.  If I make linux on one host, running Fedora Core 3, with a gcc3.4.2 everything works fine.  If I make linux on a different host, running Fedora Core 4, with a gcc 4.0.0, I get a bunch of compile warnings about  conflicting signage, and so forth.  I wonder what might be causing this.  I would not have thought there would be that much difference between the gcc's.

Thanks,
Ben Evans

$ find net -name Kconfig|xargs grep IP_MROUTE
net/ipv4/Kconfig:config IP_MROUTE
net/ipv4/Kconfig:       depends on IP_MROUTE
net/ipv4/Kconfig:       depends on IP_MROUTE

Going to read the file, I can see it's "IP: multicast routing" under the
networking configurations.
