Details:

Setting the output language to C++ and compiling the output with a C++98
compiler, compilation fails on the IAR C++ compiler (version 6.70.2.6274).

The std::vector class of the IAR compiler relies on operator= in its push_back
implementation. Defining 'stack_symbol_type &operator=(stack_symbol_type &)'
stops the compiler implicitly generating operator= for other arguments.
Specifically 'const stack_symbol_type &operator=(const stack_symbol_type &) is
missing which is needed by std::vector::push_back.

The lalr1.cc skeleton needs to be changed to also define the const operator=
for stack_symbol_type (and also others like sematic_type when using variants)
