lalr1.cc copyright block

[Alexei Khlebnikov]

Hello, Bison developers.

I've noted that when using lalr1.cc skeleton, the resulted generated
parser file does not have "special exception"

/* As a special exception, when this file is copied by Bison into a
   Bison output file, you may use that output file without restriction.
   This special exception was added by the Free Software Foundation
   in version 1.24 of Bison.  */

, while when using yacc.c, this exception is present.

Is it intended bison behaviour and bison is not going to support C++
parsers for closed-source programs?

Best Regards,
Alexei.
