453	Allow unsigned-integer64 as an FFI return type	Moritz Heidkamp	felix winkelmann	As of 4.6.3, {{{unsigned-integer64}}} is available as an FFI type for function arguments and locations but it is not yet as a return type. I see that this belongs into the {{{foreign-result-conversion}}} procedure in {{{support.scm}}} but I don't really know how exactly the conversion has to be done.	enhancement	closed	minor		compiler	4.6.x	fixed
