64// Implicit instantiation requires that all member declarations be
65// instantiated, but that the definitions are *not* instantiated.
66//
67// It's not particularly clear how this applies to enum's or typedefs;
68// both are described as declarations [7.1.3] and [7.2] in the standard,
69// however some compilers use "delayed evaluation" of one or more of
70// these when implicitly instantiating templates. We use typedef declarations
71// by default, but try defining BOOST_USE_ENUM_STATIC_ASSERT if the enum
72// version gets better results from your compiler...
73//
74// Implementation:
75// Both of these versions rely on sizeof(incomplete_type) generating an error
76// message containing the name of the incomplete type. We use
77// "STATIC_ASSERTION_FAILURE" as the type name here to generate
78// an eye catching error message. The result of the sizeof expression is either
79// used as an enum initialiser, or as a template argument depending which version
80// is in use...
81// Note that the argument to the assert is explicitly cast to bool using old-
82// style casts: too many compilers currently have problems with static_cast
83// when used inside integral constant expressions.
