[GCC-XML] Error using msvc6

[Vaidya, Jalil]

Hi,

I have sample code that uses a map of CString objects where CString is a
class derived from std::basic_string and uses a custom defined
case_insensitive_traits. The CString code is in CString.h and the class
using it is in MapOfCString.h. I have attached both the files (My
apologies if the attachments to mailing lists are considered
inappropriate). 

I am using 0.7 version of GCC-XML. When MapOfCString.h is parsed using
msvc6 as compiler setting then I get following error. The same header is
parsed using msvc8 compiler setting without any errors.

The code compiles just fine in both VC6 and VC8 (VS2005). Any ideas on
how to get this working with msvc6? Any help is much appreciated.

Thanks,
