• Visual C++ Migrating a VC 6 Project to VC 8 (aka VC 2005)

  Dev Environment: VC 8 version 8.0.50727.26 (RTM.050727-2600) OS: Win XP Pro I am migrating a VC6 project to VC8 and I'm getting an error that doesn't make a lot of sense.  First of all, the project builds fine in VC6 - no errors, but of course, some warnings.  The project uses STL heavily so that some of it (not all of it) can be built on different OSes.  After fixing 700+ errors from the initial attempt to build (mostly due to new and better C++ conformity and MFC changes in VC 8) I am now down to one error(!) and I'm stumped.  Here it is: c:\program files\microsoft visual studio 8\vc\include\istream(842) : error C224 ...Show All
