+ Revision history:

+   31 March 2004 - improved diagnostic messages and portability 
+                   (Jonathan Turkanis)
+   03 April 2004 - works on VC6 at class and namespace scope
+                 - ported to DigitalMars
+                 - static warnings disabled by default; when enabled,
+                   uses pragmas to enable required compiler warnings
+                   on MSVC, Intel, Metrowerks and Borland 5.x.
+                   (Jonathan Turkanis)
+   30 May 2004   - tweaked for msvc 7.1 and gcc 3.3

+// 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. The 
+// only pragma which is absolutely necessary here is for Borland 5.x, since 
+// W8073 is disabled by default. If enabling selected warnings is considered 
+// unacceptable, this section can be replaced with:
+//   #if defined(__BORLANDC__) && (__BORLANDC__ <= 0x600)
+//    pragma warn +st
+//   #endif
+
+// 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
