store all ordering information in pathkeys lists (which are now lists of
lists of PathKeyItem nodes, not just lists of lists of vars).  This was
a big win --- the code is smaller and IMHO more understandable than it
was, even though it handles more cases.  I believe the node changes will
not force an initdb for anyone; planner nodes don't show up in stored
rules.

Attached you'll find a (big) patch that fixes make dep and make
depend in all Makefiles where I found it to be appropriate.

It also removes the dependency in Makefile.global for NAMEDATALEN
and OIDNAMELEN by making backend/catalog/genbki.sh and bin/initdb/initdb.sh
a little smarter.

This no longer requires initdb.sh that is turned into initdb with
a sed script when installing Postgres, hence initdb.sh should be
renamed to initdb (after the patch has been applied :-) )

This patch is against the 6.3 sources, as it took a while to
complete.

Please review and apply,

Cheers,

some of the ports...

Makefile.global.

End result, if all goes well, should allow for much easier porting, since
there will no longer be a concept of a "port".  Most, if not everything,
*should* be determined by configure, or by the compiler itself.  Still
work to be done though :)

Add #include "postgres.h"
	and
    #include <sys/types.h>
