* $Log: shpadd.c,v $
* Revision 1.18 2016-12-05 12:44:05 erouault
* * Major overhaul of Makefile build system to use autoconf/automake.
*
* * Warning fixes in contrib/
*
* Revision 1.17 2016-12-04 15:30:15 erouault
* * shpopen.c, dbfopen.c, shptree.c, shapefil.h: resync with
* GDAL Shapefile driver. Mostly cleanups. SHPObject and DBFInfo
* structures extended with new members. New functions:
* DBFSetLastModifiedDate, SHPOpenLLEx, SHPRestoreSHX,
* SHPSetFastModeReadObject
*
* * sbnsearch.c: new file to implement original ESRI .sbn spatial
* index reading. (no write support). New functions:
* SBNOpenDiskTree, SBNCloseDiskTree, SBNSearchDiskTree,
* SBNSearchDiskTreeInteger, SBNSearchFreeIds
*
* * Makefile, makefile.vc, CMakeLists.txt, shapelib.def: updates
* with new file and symbols.
