Proposed patch

The compiler complains about ambiguity in calls, apparently because there is a
"using std::make_pair" in the WTF namespace (wtf/HashTraits.h) and
Structure.cpp has both "using namespace std" and "using namespace WTF".
Removing "using namespace std" makes it compile without any other changes
needed.

Compiler output:
