+// casting of pointers and references.  
+
+// In casting between different C++ classes, there are a number of
+// rules that have to be kept in mind in deciding whether to use
+// static_cast or dynamic_cast.  
+
+// a) dynamic casting can only be applied when one of the types is polymorphic
+// Otherwise static_cast must be used.
+// b) only dynamic casting can do runtime error checking
+// use of static_cast is generally un checked even when compiled for debug
+// c) static_cast would be considered faster than dynamic_cast.
+
+// If casting is applied to a template parameter, there is no apriori way
+// to know which of the two casting methods will be permitted or convenient.
+
+// smart_cast uses C++ type_traits, and program debug mode to select the

+
+//
+// Implementation
+// Makes use of the following warnings:
+//  1. GCC prior to 3.3: division by zero.
+//  2. BCC 6.0 preview: unreferenced local variable.
+//  3. DigitalMars: returning address of local automatic variable.
+//  4. VC6: class previously seen as struct (as in 'boost/mpl/print.hpp')
+//  5. All others: deletion of pointer to incomplete type.
+//
+// The trick is to find code which produces warnings containing the name of
+// a structure or variable. Details, with same numbering as above:
+// 1. static_warning_impl<B>::value is zero iff B is false, so diving an int
+//    by this value generates a warning iff B is false.
+// 2. static_warning_impl<B>::type has a constructor iff B is true, so an
+//    unreferenced variable of this type generates a warning iff B is false.
+// 3. static_warning_impl<B>::type overloads operator& to return a dynamically
+//    allocated int pointer only is B is true, so  returning the address of an
+//    automatic variable of this type generates a warning iff B is fasle.
+// 4. static_warning_impl<B>::STATIC_WARNING is decalred as a struct iff B is 
+//    false. 
+// 5. static_warning_impl<B>::type is incomplete iff B is false, so deleting a
+//    pointer to this type generates a warning iff B is false.
+//
+
+//------------------Enable selected warnings----------------------------------//
+
+// Enable the warnings relied on by BOOST_STATIC_WARNING, where possible.
+
+// 6. replaced implementation with one which depends solely on
+//    mpl::print<>.  The previous one was found to fail for functions
+//    under recent versions of gcc and intel compilers - Robert Ramey
