 Changes:
	0.1 - 	Initial Release
	0.2 - 	No longer bombs out if dbopen returns an error.
	0.3 - 	Added some support for multiple btree compares
	1.0 - 	Complete support for multiple callbacks added.
	      	Fixed a problem with pushing a value onto an empty list.
	1.01 - 	Fixed a SunOS core dump problem.
		The return value from TIEHASH wasn't set to NULL when
		dbopen returned an error.
	1.02 - 	Use ALIAS to define TIEARRAY.
		Removed some redundant commented code.
		Merged OS2 code into the main distribution.
		Allow negative subscripts with RECNO interface.
		Changed the default flags to O_CREAT|O_RDWR
	1.03 - 	Added EXISTS
	1.04 -  fixed a couple of bugs in hash_cb. Patches supplied by
		Dave Hammen, hammen@gothamcity.jsc.nasa.gov
	1.05 -  Added logic to allow prefix & hash types to be specified via
		Makefile.PL
	1.06 -  Minor namespace cleanup: Localized PrintBtree.
	1.07 -  Fixed bug with RECNO, where bval wasn't defaulting to "\n". 
	1.08 -  No change to DB_File.xs
	1.09 -  Default mode for dbopen changed to 0666
	1.10 -  Fixed fd method so that it still returns -1 for
		in-memory files when db 1.86 is used.
	1.11 -  No change to DB_File.xs
	1.12 -  No change to DB_File.xs
	1.13 -  Tidied up a few casts.     
	1.14 -	Made it illegal to tie an associative array to a RECNO
		database and an ordinary array to a HASH or BTREE database.
	1.50 -  Make work with both DB 1.x or DB 2.x
	1.51 -  Fixed a bug in mapping 1.x O_RDONLY flag to 2.x DB_RDONLY equivalent
	1.52 -  Patch from Gisle Aas <gisle@aas.no> to suppress "use of 
		undefined value" warning with db_get and db_seq.
	1.53 -  Added DB_RENUMBER to flags for recno.
	1.54 -  Fixed bug in the fd method
        1.55 -  Fix for AIX from Jarkko Hietaniemi
        1.56 -  No change to DB_File.xs
        1.57 -  added the #undef op to allow building with Threads support.
	1.58 -  Fixed a problem with the use of sv_setpvn. When the
		size is specified as 0, it does a strlen on the data.
		This was ok for DB 1.x, but isn't for DB 2.x.
        1.59 -  No change to DB_File.xs
        1.60 -  Some code tidy up
        1.61 -  added flagSet macro for DB 2.5.x
		fixed typo in O_RDONLY test.
        1.62 -  No change to DB_File.xs
        1.63 -  Fix to alllow DB 2.6.x to build.
        1.64 -  Tidied up the 1.x to 2.x flags mapping code.
		Added a patch from Mark Kettenis <kettenis@wins.uva.nl>
		to fix a flag mapping problem with O_RDONLY on the Hurd
        1.65 -  Fixed a bug in the PUSH logic.
		Added BOOT check that using 2.3.4 or greater
        1.66 -  Added DBM filter code
        1.67 -  Backed off the use of newSVpvn.
		Fixed DBM Filter code for Perl 5.004.
		Fixed a small memory leak in the filter code.
        1.68 -  fixed backward compatibility bug with R_IAFTER & R_IBEFORE
		merged in the 5.005_58 changes
        1.69 -  fixed a bug in push -- DB_APPEND wasn't working properly.
		Fixed the R_SETCURSOR bug introduced in 1.68
		Added a new Perl variable $DB_File::db_ver 
        1.70 -  Initialise $DB_File::db_ver and $DB_File::db_version with 
		GV_ADD|GV_ADDMULT -- bug spotted by Nick Ing-Simmons.
		Added a BOOT check to test for equivalent versions of db.h &
		libdb.a/so.
        1.71 -  Support for Berkeley DB version 3.
		Support for Berkeley DB 2/3's backward compatibility mode.
		Rewrote push
        1.72 -  No change to DB_File.xs
        1.73 -  No change to DB_File.xs
        1.74 -  A call to open needed parenthesised to stop it clashing
                with a win32 macro.
		Added Perl core patches 7703 & 7801.
        1.75 -  Fixed Perl core patch 7703.
		Added support to allow DB_File to be built with 
		Berkeley DB 3.2 -- btree_compare, btree_prefix and hash_cb
		needed to be changed.
        1.76 -  No change to DB_File.xs
        1.77 -  Tidied up a few types used in calling newSVpvn.
        1.78 -  Core patch 10335, 10372, 10534, 10549, 11051 included.
        1.79 -  NEXTKEY ignores the input key.
                Added lots of casts
        1.800 - Moved backward compatibility code into ppport.h.
                Use the new constants code.
        1.801 - No change to DB_File.xs
        1.802 - No change to DB_File.xs
        1.803 - FETCH, STORE & DELETE don't map the flags parameter
                into the equivalent Berkeley DB function anymore.
        1.804 - no change.
        1.805 - recursion detection added to the callbacks
                Support for 4.1.X added.
                Filter code can now cope with read-only $_
