Yeah, i didn't provide such an overload to avoid ambiguity
between port numbers and flags arguments.
Using the string "80" will work on windows even though
AI_NUMERICSERV isn't defined by the implementation. You can also
pass the numeric_service flag to optimise the call on platforms
where it is supported, but it isn't absolutely required to have
the numeric string converted.
Another approach (although not strictly meeting your
requirements) is to use the endpoint::port() setter function
