waiting for approval).
(Fortran, BTYacc): Remove, there does not seem to be demand.

 They should not: it is not documented.  But if they need to, let's
 find something clean (not like YYLSP_NEEDED...).

 Some history of Bison and some bibliography would be most welcome.
 Are there any Texinfo standards for bibliography?

-* BTYacc
-See if we can integrate backtracking in Bison.  Charles-Henri de
-Boysson <de-boy_c@epita.fr> has been working on this, but never gave
-the results.
-
-Vadim Maslow, the maintainer of BTYacc was once contacted.  Adjusting
-the Bison grammar parser will be needed to support some extra BTYacc
-features.  This is less urgent.
-
-** Keeping the conflicted actions
-First, analyze the differences between byacc and btyacc (I'm referring
-to the executables).  Find where the conflicts are preserved.
-
-** Compare with the GLR tables
-See how isomorphic the way BTYacc and the way the GLR adjustments in
-Bison are compatible.  *As much as possible* one should try to use the
-same implementation in the Bison executables.  I insist: it should be
-very feasible to use the very same conflict tables.

-** Adjust the skeletons
-Import the skeletons for C and C++.
