In addition, default (Yacc-like) output from Bison allows unrestricted use and redistribution of C files produced by (as opposed to contained in) Bison. This is not true of other modes of operation (GLR parsers in particular). Amongst the Bison maintainers, I would again like to raise the issue of whether other skeletons (GLR in particular) should have the same terms as the default output. My feeling is that they should, and that placing Bison output (as opposed to Bison itself) under the GPL is undesirable. Paul Hilfinger
