Hello,
I have read the "Conditions for Using Bison" on
page 3 of the Bison 2.0 documentation.
The first lines say:
<quote>
As of Bison version 1.24, we have changed the
distribution terms for yyparse to permit using Bison's output in nonfree
programs when Bison is generating C code for LALR(1) parsers
<end quote>
Does this mean that this only applies when
using the skeleton file yacc.c and that this NOT applies when using the
skeleton files glr.c or lalr1.cc? This would mean that you can not make glr
parsers (%glr-parser) or c++ parsers if you want to use the output in nonfree
programs.
The last lines of the "Conditions for using Bison"
mention:
<quote>
You can tell whether the exception applies to your
'.c' output file by inspecting it to see whether it says
"As a special exception, when this file is copied
by Bison into a Bison output file, you may use that output file without
restriction."
<end quote>
If I inspect the skeleton files yacc.c , glr.c and
lalr1.cc I see that only yacc.c contains this text.
Is this correct? If so, could you explain why this
distinction is made?
Regards,
--Michel
