Comment (by robe):

 Actually this may be more than a windows issue or I'm just being stupid.
 I get the same answers on my CentOS dev box when comparing my 1.3.6
 database with 1.4 install. Both in theory are sharing the same proj and
 same datum shift since I didn't recompile proj when compiling PostGIS 1.4
 for this particular install

 So i really don't know which one is right at this point.  If its a mistake
 in teh dataum shift, then I must be doing the same thing wrong on my linux
 installs
