c++: workaround portability issue
On some systems (x86_64-pc-solaris2.11), with Developer Studio 12.5's
CC, we get:
".../include/CC/Cstd/vector.cc", line 127: Error: Cannot assign const yy::parser::stack_symbol_type to yy::parser::stack_symbol_type without "yy::parser::stack_symbol_type::operator=(const yy::parser::stack_symbol_type&)";.
".../include/CC/Cstd/vector", line 475: Where: While instantiating "std::vector<yy::parser::stack_symbol_type>::__insert_aux(yy::parser::stack_symbol_type*, const yy::parser::stack_symbol_type&)".
".../include/CC/Cstd/vector", line 475: Where: Instantiated from non-template code.
1 Error(s) detected.
Don't expect __cplusplus to be always defined. If it's not, consider
this is C++98.
Reported by Nelson H. F. Beebe.
* data/c++.m4, data/lalr1.cc, examples/c++/variant.yy, tests/local.at,
* tests/testsuite.h:
An undefined __cplusplus means pre C++11.
