      - Put operator "->" back into parser. Note that :foo->bar means the
        C term, but :foo ->bar means the operator "->".

Tue Apr 28 15:49:07 CEST 1998

      - Added exec sql disconnect command.
      - Allow varchar in C to be written in uppercase too.
      - Added whenever option "do break;"

Wed Apr 29 09:17:53 CEST 1998

      - Corrected parsing of C comments.
      - Also allow C++ style comments.
      - Make sure not found is only checked after commands that could
          return it.
      - Added error codes, see ecpgerror.h for details.
      - Added "exec sql <TransactionStmt> release" as disconnect statement
        for compatibility issues.

Thu Apr 30 10:42:10 CEST 1998

      - Added a -t option to disable automatic transaction start.
      - Added sqlerrd[] to sqlca struct.
      - Give back number of tuples affect in sqlca.sqlerrd[2].

Thu Apr 30 13:36:02 CEST 1998

      - Make the return code different in case of different errors.

Wed May  6 11:42:48 CEST 1998

      - Free memory if possible
      - Some bugfixes for bugs I found while changing the memory
          allocation code
      - Now able to fill complete array with one call (see test1.pgc for
          an example)
      - Set version to 2.3.0
      - Set library version to 2.1
