[Mingw-users] mingw compiler bug?

[Bob R. <bob...@co...>]

Hi,

If I compile this, it fails with mingw,
$ g++ --version                                                                                         
g++.exe (GCC) 3.4.2 (mingw-special)                                                                     

  #include <sstream>

  class logstream : public ::std::basic_ios<wchar_t> {
    public:
      logstream ();
  };

The error is,
  C:/mingw/bin/../lib/gcc/mingw32/3.4.2/../../../../include/c++/3.4.2/bits/basic_ios.h: In instantiation o
  f `std::basic_ios<wchar_t, std::char_traits<wchar_t> >':                                                
  main.cpp:3:   instantiated from here                                                                    
  C:/mingw/bin/../lib/gcc/mingw32/3.4.2/../../../../include/c++/3.4.2/bits/basic_ios.h:67: error: no type 
  named `pos_type' in `struct std::char_traits<wchar_t>'                                                  

After looking at this error for a while, I don't think it actually is an
error.

Changing the wchar_t to a char above does compile. This isn't my code,
so I can't easily change it.

On ubuntu linux, g++ version 3.3.6, 3.4.6, 4.0.4 20060630 and 4.1.2 20060928,
both wchar_t and char work in the code above.

Any suggestions?

Thanks,
Bob Rossi
