Change box terminology from "length" to "width".
Use length terminology in common with other geometric types (usually perimeter).
Fix bugs in line arithmetic which resulted in bad intersection calculations.
Deprecate temporary unstored slope fields.
Check explicitly for intersections at endpoints to avoid rounding ugliness.
Add center() routines for lseg, path, polygon.
Add distance() routines for circle-polygon, polygon-polygon.
Check explicitly for points and polygons contained within polygons
using an axis-crossing algorithm. (Old code just checked bounding boxes).
Add routine to convert circle-box.
*whew*
This matches the behavior of the original formatting for abstime.
Repair datetime + timespan date arithmetic for year boundaries.
From patch submitted by Dave Skinner.
the problem only manifests itself when adding years/months and hours
when the hours:minutes:seconds pushes over midnight.
Fix interpretation of times with explicit timezone when the timezone is
in daylight savings time and is not the default timezone.
Allow interpretation of explicit timezone when it is specified as two words:
<standard time> DST". For example, "MET DST" (Middle European Time Daylight
Savings Time). This syntax is found in the zic package on Linux boxes at least.

smgrclose(reln->rd_rel->relsmgr, reln);
- it avoids memory leaks in SMGR & VFD.
RelationFlushRelation():
there is no more call FileInvalidate(RelationGetSystemPort(relation));
- invalid (FileInvalidate() expects File, not SMGR' fd)
- unuseful anyway.
Subject: [PATCHES] Re: [PORTS] AIX 6.1 fixes...
Here are the patches for the two things that wouldn't make it thru the AIX
compiler. The geo_ops.c change is harmless I believe. The nbtcompare.c patch
fixes me, but I don't know about any other ports. Maybe wait on that one
until Vadim decides what to do about the unsigned vs signed chars varlena
issue.
Bring optional new-storage date and time up to date and test.
This new storage format should fix the "Sparc gcc -O2 bug".
(Enable new code with USE_NEW_DATE and USE_NEW_TIME in dt.h)
