Only case that I can think of where 0.0.0.0 handling will break apps
is in lazy network programming. Consider the psuedo-code:
ip_addr = "0.0.0.0"
for (each_ip in valid_addresses)
On Windows, this would likely cause a catchable error. On Linux (at
least), the socket connection may succeed. I think someone said C&C3
is affected by this inconsistency between Linux and Windows INADDR_ANY
handling; this is probably why :P
Until someone demonstrates a real need for this (with appropriate test
