[Nbd] Problems getting nbd-2.7.x to compile

["heretic@...15..." <heretic@...15...>]

I cannot get nbd over 2.7 to compule.  2.6.0 compiles fine, 2.7.[01] give:

nbd-server.c: In function `mainloop':
nbd-server.c:674: error: `NBD_CMD_DISC' undeclared (first use in this
function)
nbd-server.c:674: error: (Each undeclared identifier is reported only once
nbd-server.c:674: error: for each function it appears in.)

Thoughts?
