 * $Log: dbfadd.c,v $
 * Revision 1.3  2009/06/04 04:25:19  we7u
 * Getting rid of compiler warnings due to unused variable.
 *
 * Revision 1.2  2009/06/03 22:24:19  we7u
 * Adding includes for string.h to get rid of compiler warnings.
 *
 * Revision 1.1  2006/11/10 21:48:09  tvrusso
 * Add shapelib as an internal library, and use it if we don't find an external
 * one.
 *
 * Make a loud warning if we do so, because the result of this is that we'll
 * have a bigger executable.
 *
 * This commit is bigger than it needs to be, because it includes all of
 * shapelib, including the contrib directory.
 *
 * Added an automake-generated Makefile for this thing.
 *
 * Builds only a static library, and calls it "libshape.a" instead of
 * "libshp.a" so that if we use ask to use the static one while there is
 * also an external one installed, the linker doesn't pull in the shared
 * library one unbidden.
 *
 * This stuff can be tested on a system with libshp installed by configuring with
 * "--without-shapelib"
 *
 * I will be removing Makefile.in because it's not supposed to be in CVS.  My
 * mistake.
 *
 * Revision 1.7  2002/01/15 14:36:07  warmerda
 * updated email address
 *
 * Revision 1.6  2001/05/31 18:15:40  warmerda
 * Added support for NULL fields in DBF files
 *
 * Revision 1.5  1999/11/05 14:12:04  warmerda
 * updated license terms
 *
 * Revision 1.4  1998/12/03 16:36:06  warmerda
 * Added stdlib.h and math.h to get atof() prototype.
 *
 * Revision 1.3  1995/10/21 03:13:23  warmerda
 * Use binary mode..
 *
 * Revision 1.2  1995/08/04  03:15:59  warmerda
 * Added header.
