- Get all functions prototyped or at least defined before use.
- Make code compile (Mostly) clean with -Wall set
- Start to reduce the degree to which DES aka libdes is built in.
- get all functions to the same uniform standard of definition:
int
foo(a, b)
int a;
int *b;
{
:
}
- fix numerous bugs exposed by above processes.
Note - this replaces the previous work which used an unpopular function
definition style.

|
* the host whose official name is "MENELAUS.MIT.EDU", the name "menelaus"

* rcmd servers (rlogin, rsh, rcp) is of the form "rcmd.host@realm"
|
|
* where "host"is the lowercase for of the host name ("menelaus").
|
|
* This should go away: the instance should be the domain name
|
|
* (MENELAUS.MIT.EDU). But for now we need this routine...
|
|

|
|
* A pointer to the name is returned, if found, otherwise a pointer
|
|
* to the original "alias" argument is returned.
