with 1_38_0 I can't get any code compiling related to spirit; all that worked
with 1_34_1.
According to those compiler warnings I'm using now the "classic" versions,
but this doesn't help. Consider
#include <boost/spirit/include/classic_core.hpp>
namespace OKlib {
  namespace Parser {
    template <typename CharT = char, typename ParseIterator_ = const CharT*>
    class ParserBase {
    public :
      typedef CharT char_type;
      typedef ParseIterator_ ParseIterator; 
      typedef boost::spirit::scanner<ParseIterator> scanner_type;
This used to work (with boost/spirit/core.hpp), but now I get the error message
(gcc version 4.1.2):
ParserBase.hpp:27: error: ISO C++ forbids declaration of ‘scanner’ with no type
ParserBase.hpp:27: error: typedef name may not be a nested-name-specifier
ParserBase.hpp:27: error: expected ‘;’ before ‘<’ token
where line 27 is the line where scanner_type is defined. ???
Did the definition of class template scanner change (apparently it now has two
parameters)?
No.  The namespace changed.  Unless
BOOST_SPIRIT_USE_OLD_NAMESPACE
is defined, the namespace is boost::spirit::classic.
