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.
