I found a following comment for raw command in
# raw.c does not compile on 2.2.*.
# find out later where it does and add tests to config
But util-linux-2.10c-rhconfig.patch contains following lines.

I think ADD_RAW should NOT be set for 2.2.x kernel.
Red Hat 7 uses kernel-headers from 2.4, so ADD_RAW should be ok.
