[open-cobol-list] CVS update + 4

[Roger While]

Implement syntax EXTERNAL AS Literal for WS data items.
Implement testsuite check for such.

eg.
Prog1
01  myvar   pic x(10) external as "EXT-VAR".

Prog2
01  ext-var  pic x(10) external.

and, of course, vice-versa.

Note the "AS" literal IS case sensitive so
'AS "ext-var"' will not work as Cobol works
in upper case.
