|
| +// It's not particularly clear how this applies to enum's or typedefs;
|
| +// both are described as declarations [7.1.3] and [7.2] in the standard,
|
| +// however some compilers use "delayed evaluation" of one or more of
|
| +// these when implicitly instantiating templates. We use typedef declarations
|
| +// by default, but try defining BOOST_USE_ENUM_STATIC_ASSERT if the enum
|
| +// version gets better results from your compiler...
|
| +//
|
| +// Implementation:
|
| +// Both of these versions rely on sizeof(incomplete_type) generating an error
|
| +// message containing the name of the incomplete type. We use
|
| +// "STATIC_ASSERTION_FAILURE" as the type name here to generate
|
| +// an eye catching error message. The result of the sizeof expression is either
|
| +// used as an enum initialiser, or as a template argument depending which version
|
| +// is in use...
|
| +// Note that the argument to the assert is explicitly cast to bool using old-
|
| +// style casts: too many compilers currently have problems with static_cast
|
| +// when used inside integral constant expressions.
