Translation error with a source code containing a variable initialized to empty string. #43

Open-COBOL-ESQL cannot convert the following source code. Open-COBOL-ESQL does not accept source code containing a variable initialized to an empty string.

       IDENTIFICATION              DIVISION.
       PROGRAM-ID.                 a.
       DATA                        DIVISION.
       WORKING-STORAGE             SECTION.
       01 VAL PIC X(5) VALUE "".
       PROCEDURE                   DIVISION.
           DISPLAY "Hello".
           STOP RUN.

If opensource COBOL compiles the source code, compiling succeeds while cobc displays warning messages.

a.cbl:5: Warning: Alphanumeric literal has zero length
a.cbl:5: Warning: A SPACE will be assumed

I merged the fix to v1.3.
