[boost] [concept_check.hpp] unreferenced formal parameter line 227

Hi, I was wondering if anybody has thought about adding a #else to the #if !defined(_ITERATOR) to ignore the unused variable warning in AssignableConcept::const_constraints() you get when compiling on VC7.1 ? (Or am I missing something subtle about the situation) Thanks Kevin -- | Kevin Wheatley, Cinesite (Europe) Ltd | Nobody thinks this | | Senior Technology | My employer for certain | | And Network Systems Architect | Not even myself |
