receiving broadcasts from host zero in a subnet?

I am attempting port a program to linux that listens to broadcast UDP
packets from a particular device while performing a network boot. This
UDP broadcast is received OK if it is from the all zeroes 0.0.0.0 address
to the all ones broadcast address. But if the packet is from for example
192.168.1.0 to 192.168.1.255 (with subnet mask 255.255.255.0) the packet
does not appear to be received on an UDP socket bound to INADDR_ANY. The
device in questions its subnet but not its IP address so it uses this
peculiar broadcast. Is there any special rule I need to enable to receive
these kind of broadcasts?
