I do too. I can take Tobin's original patch and manually revert this
chunk then, ie.
- verdict |= (stpc->root[2+i] ^ c->root_addr[i]) &
- c->root_addrmsk[i];
+ verdict |= (stpc->root[2 + i] ^ c->root_addr[i]) &
+ c->root_addrmsk[i];

Then you can follow up with a patch to add this function.
Just a suggestion, let me know if this is fine with you.
