9503	Compile error C4996 with boost::uuids:uuid and vc2012	Craig Hutchinson <craig@…>	Andy Tompkins	"When compiling uuid under vc2012 with safe check enabled the C4996 warning is escalated to ERROR status.

The pragma that already exists in boost_1_55_0\boost\uuid\uuid.hpp does not cater for this:
{{{
#pragma warning(disable : 4996)
}}}

I have attached a modified uuid which uses std::array as a sensible solution - this was actually commented in the original code. Now this enables safe iterators for compiler checks to be performed and removed any need for the #pragma pre-processor directives. There may be other changes needed elsewhere(i.e. &*uuid.begin() in functions needing void*)."	Patches	closed	To Be Determined	uuid	Boost 1.55.0	Problem	wontfix	C4996 vc2012
