Hello,

I am using the DJGPP 3.02 version for Windows 2000 and seem to be
experiencing a problem that I hope you can help with.  The problem is that
when I declare a function parameter of type
std::basic_string<Char_t>::iterator the compiler does not seem to recognize
that std::string::begin() returns a value of that type and complains that it
cannot find a match for std::__normal_iterator<char*,
std::basic_string<char,  std::char_traits<char>, std::allocator<char> > >,
which is in fact what std::basic_string<Char_t>::iterator is a typedef for.
If I modify my parameter declaration to use the long
std::__normal_iterator<> declaration directly, then it works just fine.

Is this a bug?  The following code demonstrates the problem:

// test driver for iterator problem

#include <string>
#include <iostream>

template <typename Char_t>
std::basic_string<Char_t>::iterator
ShowChars(std::basic_string<Char_t>::iterator startPos,
          std::basic_string<Char_t>::iterator endPos)
{
  for( ; !(startPos == endPos); ++startPos)
  {
    std::cout << *startPos;
  }

  std::cout << std::endl;
}

int main()
{
  std::cout << "Start of test program" << std::endl << std::endl;

  std::string    str("Hello, World!");

  ShowChars(str.begin(), str.end());

  std::cout << std::endl << "End of test program" << std::endl;

  return 0;
}

// end of this file

Compiling this file with the -v option generates the following output:

test4.cpp: In function `int main()':
test4.cpp:25: no matching function for call to
   `ShowChars(std::__normal_iterator<char*, std::basic_string<char,
   std::char_traits<char>, std::allocator<char> > >,
   std::__normal_iterator<char*, std::basic_string<char,
   std::char_traits<char>, std::allocator<char> > >)'

Looking through the header files I can see that bits\basic_string.h provides
the following typedef: 

       typedef __normal_iterator<pointer, basic_string>
iterator;

So it looks to me, IMHO, as if the code should work as is.
