Instantiate lexers with std::string, not flex_string 
The main programs of these samples use std::string to instantiate
their context object, which propagates down to the type of the lexer.
The manual instantiations use BOOST_WAVE_STRINGTYPE a.k.a flex_string
and so do not satisfy the missing symbols, giving a link error.
