此文件包含了在linux下实现tpr-tree索引的源代码

Dana A. Naideth from UC Santa Barbara reported a bug:

** Experimental testbed for access methods for moving points
   1999--2001, Aalborg University

Tree> create mytree tprtree 2
Table mytree created as type tprtree.
current time is 0
page size is 1024
TPRTree> l
Table mytree closed.
Tree> open mytree
Error opening table.
Tree>

Fixed by modifying GiSTfile::Open() in libGiST/GiSTfile.cpp.

Noticed by Simonas Saltenis: When in RTsortArray::SortNTimes numNodes
is 1, in rear cases floating point imprecision may lead assert to fire
in part of the code where "fudge" is redistributed. 

Solved by adding a line in index/rtbulksort.cpp,
RTsortArray::SortNTimes, that exits the method if numNodes == 1.

Three things are corrected in the gcc 3.3.x release:

- A line was added in index/sgram.cpp, function ParseCommands(), to handle
 an unexpected EOF in the command file

- The GiSTcache::Add was corrected in GiSTfcnt.cpp to work correctly
  when there is only one page (the root) in the buffer

- A bug in RTnode::RstarSplit(), in index/rtnode.cpp, was
  corrected. The bug caused to choose the split index always from the
  end-point sorting for the chosen axis.
