include files properly...yet, slowly...

access/tupdesc.h
	catalog/pg_attribute.h
	nodes/pg_list.h
		nodes/nodes.h
	access/attnum.h

	Based on include files require by htup.h, as:

	access/htup.h
		storage/itemptr.h
			storage/block.h
			storage/off.h
		utils/nabstime.h
			<time.h>

Pointed out by Bryan (in a subtle way *grin*)

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

Add #include "postgres.h" as required

add #include "postgres.h"

add #include "postgres.h"

	#include "postgres.h"
	#include "c.h"

Added missing include files

Add some missing include files

remove postgres.h from fmgr.h creation

won't be...

*should* be intelligent enough that:

#if defined(__FreeBSD__) works, where __FreeBSD__ is actually defined
by the compiler itself.

Makefile.global used to have -DPORTNAME_<port> -D<port> as part of the flags
for gcc while all occurances of PORTNAME_<port> slowly get removed from
the source tree...

removing duplicate names.

Added needed include file.
