	  database will not be truncated in NEWDB mode until the

	  one computer.  Also added the flags "-r" for opening the
	  database as a READER and "-n" for opening the database as
	  a NEWDB writer.  The default mode remains the WRCREAT mode.

	* Various source files, changed the data types of various
	  variables from int to long.  This should not make any difference
	  to systems where sizeof(int) = sizeof(long).  It should make
	  it easier to move to other systems.

	* gdbmstore.c: Added a check for NULL key or content dptr.  Due to
	  NULLs being used as error indications, data cannot be NULL also.

	* gdbmfetch.c, gdbmseq.c, fetch.c: Added checks for zero sized
	  key and content so malloc will not try to allocate zero bytes.

        * gdbmconst.h: Added this file so that all constants are in one
	  central place.  A few constants can be changed without changing
	  the header sizes.

	  pointer in ...ca_data.dptr.

	* gdbmdelete.c: Added code to more completely remove the
	  cache entry for a deleted item.

	* gdbmreorg.c: Added code to finish the transfer of information
	  from the new_dbf to the orginal dbf.

Fri May 30 08:29:16 1990  Phil Nelson  (phil at unicorn.wwu.edu)

	* gdbmstore.c: Changed a strncpy to bcopy.

Tue May 15 09:55:21 1990  Phil Nelson  (phil at unicorn.wwu.edu)

	* Version 1.3 released.

	* systems.h: Changed the defines for alloca to use the
	  name builtin_alloca to depend on BUILTIN_ALLOCA instead
	  of __GNUC__.  Added a definition of BUILTIN_ALLOCA for
	  GNUC and for sun sparc.

Fri May 11 12:15:56 1990  Phil Nelson  (phil at unicorn.wwu.edu)

	* systems.h: Removed the include for <sys/types> and now
