Akim Demaille 2142e59155 c++: demonstrate custom error messages in the examples

Let's use c++/glr to demonstrate custom error messages in C++ (not
just in glr2.cc).

* examples/c++/glr/c++-types.yy (report_syntax_error): New.
* examples/c++/glr/c++-types.test: Adjust.
* examples/c/bistromathic/parse.y: Comment changes.
* tests/local.at (AT_YYERROR_DEFINE(c++)): Use a nicer way to print
the lookakead's name.

This example demonstrates the use of GLR parsers to handle (local) ambiguities in the C++ language. See the node "Merging GLR Parses" in Bison's documentation.

It uses (Bison) variants to store objects as semantic values. It also demonstrates custom error messages in C++.
