Library for writing RTF files for both BC++ 5.02 and VC++ 2010

I'm looking for a library (LIB/DLL) for writing RTF or MS-Word files which is available for both Borland C++ 5.02 and VC++ 2010. So, this "project" simply consists in providing such a library. Please note that usually for Borland C++ it is possible to get the import LIB file using the IMPLIB utility. Of course I would also like that the library is well documented.
