	* Portability fix to lexpgn.l

	* Changes to lexpgn.l to handle some special
	  cases.

	* Portability fix to lexpgn.l

2003-06-19 Simon Waters <[e-mail]>      

	* Add "--easy" flag to command line.

	* Add "--manual" flah to command line.

	* const declaration for progname removed to 
	  resolve problems with other compilers.

	* Reapply earlier fix to ensure the players
	  names for white and black are fixed which got
	  overwritten with pgn parser merge.

	* Remove GNU tool derived files from CVS to save
	  space and avoid problems with timestamps.

	* Tell xboard sigint=0 to avoid workaround on Solaris.

	* Various code clean-ups.

	* Redefine DRAWSCORE to 0, faster, and avoids excessive
	  draw penalties.

2003-06-13 Simon Waters <[e-mail]>      

	* Use CalcHashSize in main.c

	* Check HashSize return code in cmd.c

	* Put maximum check in CalcHashSize

2003-06-12 Simon Waters <[e-mail]>      

	* Convert autoconf to AX_CREATE_STDINT_H from AC_CREATE_STDINT_H

	* Changes suggested by latest "autoscan" including tests
	  for functions we can't do without.

	* Changes required to merge DAW contribution below.

2003-06-12 David A. Wheeler <[e-mail]> 
           (Originally 2002-10-03 merged SRW)
	   
	* Rewrote PGN reader so that it fully handles the PGN standard
	  and common nonstandard variants of PGN, including PGN {} comments,
	  ; comments, varying newline conventions (Unix, Windows, MacOS),
	  FEN starting positions, multiple tags, and so on.
	  If a game is being read in with pgnload,
	  data is kept so it can be written back out later by pgnsave
	  (so that later on, annotations won't lose existing data).
	  The new reader is implemented using flex/lex, which eliminates
	  
	* Added support for not-quite-valid SAN moves, so that games
	  with such entries are still read correctly.  This includes
	  "capture-only" notation like "KxN" (King takes Knight),
	  the use of "P" for pawns, and
	  lower-case versions of many pieces (e.g., "k" for King) - note
	  that Bishops MUST be upper case (since "b" is a column identifier).

	* Added a script named "gnuchessx", which simply invokes gnuchess
	  with the "xboard" option.  This means that GNU Chess 5 now
	  automatically supports Xboard, just like GNU Chess 4 did.

	* Tidy up hashsize calculation, fix segfault

2003-06-09 Simon Waters <[e-mail]>
