FDK8.0 with VS.NET 2003

I have a frame client that was built using FDK 7.2 and VS.NET 2003. Now I have upgraded to FDK 8.0/Frame 8.0, but VS.NET in use is still 2003. I read in the posts that to make FDK 8.0 work with VS.NET 2003, we have to make the following changes:<br /><br />#include <sys/types.h><br />#include <sys/stat.h><br /><br />int _stat32( const char *path, struct _stat *buffer ) { return <br />_stat(path, buffer); }<br />int _wstat32( const wchar_t *path, struct _stat *buffer ) { return <br />_wstat(path, buffer); }<br /><br />long _ftol( double );<br />long _ftol2_sse( double dblSource ) { return _ftol( dblSource ); }<br /><br />After making the above changes, I can build the solution and generate the DLL. However, in the main application (that references this frame client)... i get the following error:<br /><br />"IXPFrameLib error LNK2019: unresolved external symbol __ftol2_sse referenced in function _F_MetricFloat"<br /><br />Are we required to make any other changes? Is FDK8.0 backward compatible with FDK7.1?<br /><br />Thanks...
