+// PFTO version is used to specify the last argument of certain functions
+// Function it is used to support  compilers that fail to support correct Partial 
+// Template Ordering
+#include <boost/config.hpp>
+
+// some compilers can use an exta argument and use function overloading
+// to choose desired function.  This extra argument is long in the default
+// function implementation and int for the rest.  The function is called
+// with an int argument.  This first attempts to match functions with an
+// int argument before the default one (with a long argument).  This is
+// known to function with VC 6.0. On other compilers this fails (Borland)
+// or causes other problems (GCC).  note: this 
+
+#if defined(BOOST_NO_FUNCTION_TEMPLATE_ORDERING)
+    #define BOOST_PFTO long
+#else
+    #define BOOST_PFTO
+#endif
+
+// here's another approach.  Rather than use a default function - make sure
+// there is no default at all by requiring that all function invocations
+// have a "wrapped" argument type.  This solves a problem with VC 6.0
+// (and perhaps others) while implementing templated constructors.
