This includes all of the 'Internet' headers and definitions used across
|

|
modules, including those for handling timeouts. No changes should be needed
|
||
|
|
for any version of Unix with Internet (IP version 5) addressing, but would be
|
||
|
|
for other addressing domains. It needs <sys/socket.h> only because AF_INET is
|
||
|
|
needed by gethostbyaddr and is defined there rather than in <netdb.h>, for some
|
||
|
|
damn-fool reason. */

kludges to keep 32-bit address dependencies out of the main body of internet.c,
