Remove 'unused variable' from dt.c

of endian.h.  I figure that if it exists it's pretty sure that it has
the byte order information and we may catch some other ports without
any further testing.

include crypt.h in password.c if crypt.h does exist

Subject: [HACKERS] password authentication

This patch adds support for plaintext password authentication.  To use
it, you add a line like

host         all         0.0.0.0       0.0.0.0           password  pg_pwd.conf


to your pg_hba.conf, where 'pg_pwd.conf' is the name of a file containing
the usernames and password hashes in the format of the first two fields
of a Unix /etc/passwd file.  (Of course, you can use a specific database
name or IP instead.)

Then, to connect with a password through libpq, you use the PQconnectdb()
function, specifying the "password=" tag in the connect string and also
adding the tag "authtype=password".

I also added a command-line switch '-u' to psql that tells it to prompt
for a username and password and use password authentication.

Fixed

Essentially, config.h now includes an 'os.h', which is created via
configure by linking a "port.h" file from the port directory to the
include directory.

Going to try to merge backend/port in similar ways

aren't doing anything anyway

	sigprocmask, setsid and waitpid

Especially for nextstep systems

Awaiting for a context diff from Gregor to complete changes for the nextstep
port

Remove references to NEED_UNION_SEMUN from include/config.h.in and
from include/storage/ipc.h, replacing it with a single HAVE_UNION_SEMUN

to include inet_aton.c if required

clean up some of the readline code in config.h.in

whereby timezone isn't an int, but tzset() exists...

This isn't a definitive fix, as there is probably an easier way of
fixing the bug...

From: Keith Parks

from a #define to a run-time option '-e'

Man page was updated to reflect new option

Added a README.readline file until configure is integrated to *try* and
explain the way things stand.

Removed a stray configure .in file

Add some code to make psql happy with a system where there is *no*
history code available, but there is readline code...

bug causes compilation to fail on alpha, the second causes a compiler
in this environment

to reflect what configure is going to define when the time comes

See message to hackers@ mailing list concerning this...

Fixed them, and am re-committing

for switch over to configure

#if defined(aix)
#define TERMIOS_H_LOCATION <termios.h>
#else
#define TERMIOS_H_LOCATION <sys/termios.h>
#endif

libpq/fe-exec.c modified so that location of termios.h is determined
by whether HAVE_TERMIOS_H is defined or not, in preparation for switch
to configure

Cleaned out alot of the #define that can be auto-detect'd by
configure from config.h...
