Im getting nfsroot build error on 2 configs, both carried forward
from good rc4 and from rc3-mm1 builds.
turning off nfsroot fixes the err.

A little digging suggests the problem is in here:

git-klibc.patch:13607:-u32 root_server_addr = INADDR_NONE;    /* Address 
of NFS server */
git-klibc.patch:13840:-    if (root_server_addr == INADDR_NONE)
git-klibc.patch:13841:-        root_server_addr = ic_servaddr;
git-klibc.patch:14682:- *  need to have root_server_addr set _before_ 
IPConfig gets called as it
git-klibc.patch:14752:-         && root_server_addr == INADDR_NONE
git-klibc.patch:14806:-    if (root_server_addr == INADDR_NONE)
git-klibc.patch:14807:-        root_server_addr = addr;
git-klibc.patch:14842:-    printk(", rootserver=%u.%u.%u.%u", 
NIPQUAD(root_server_addr));
git-klibc.patch:78496:+static u_int32_t root_server_addr;
git-klibc.patch:78882:+    s = getenv("root_server_addr");
git-klibc.patch:78884:+        root_server_addr = strtoul(s, NULL, 10);
git-klibc.patch:78900:+    if ((servaddr = root_server_addr) == 
INADDR_NONE) {


Im likely to try taking 'static' off of line 78496,
but that lands in: devel-akpm/usr/klibc/tests/nfs_no_rpc.c
so I suspect I dont know the proper fix.
or indeed, whether it isnt a bonehead error.


thanks in advance
