Hartmut,

thanks for your help, but this issue is still alive ;)

Just to be sure I did everything right, I took the entire head revision of boost and compiled it.
I had no problems in the relevant libs.

I also saw your changes in the cpp_context.hpp. The only problems I still get compiler errors
using the flexi_string as described before. May usage scenario:

token_type::string_type str("some string");
if(ctx.is_defined_macro(str))
{
  ...
}

There is still the iterator derefernece compiler error in the cpp_macromap.hpp:

e:\boost\include\boost-1_35\boost\wave\util\cpp_macromap.hpp(396) : error C2228: left of
'.get_value' must have class/struct/union
        type is 'const char'
        e:\boost\include\boost-1_35\boost\wave\cpp_context.hpp(198) : see reference to function
template instantiation 'bool boost::wave::util::macromap<ContextT>::is_defined<const
char*>(const IteratorT &,const IteratorT &)' being compiled
        with
        [
            ContextT=boost::wave::context<token_groups::str_iter_type,token_groups::lex_iter_type>,
            IteratorT=const char *
        ]
        e:\projects\inpecting_wave\inpecting_wave\header_processor.cpp(178) : see reference to
function template instantiation 'bool
boost::wave::context<IteratorT,LexIteratorT>::is_defined_macro<boost::wave::cpplexer::lex_token<>::string_type>(const
StringT &)' being compiled
        with
        [
            IteratorT=token_groups::str_iter_type,
            LexIteratorT=token_groups::lex_iter_type,
            StringT=boost::wave::cpplexer::lex_token<>::string_type
        ]
e:\boost\include\boost-1_35\boost\wave\util\cpp_macromap.hpp(396) : error C2228: left of '.c_str'
must have class/struct/union

the line:
string_type name ((*it).get_value().c_str());

Still tries to call get_value on const char type.

With Kind Regards,

Ovanes
