Adding support for optional_argument in src/port would be the best
solution for long-term purposes. So +1 for it or we'll be limited in
the future as well. Here is for example attached a proof-of-concept
patch that it is not that complicated to add support for optional
arguments... Interestingly, the current implementation dates of 2003
in 939a59f and has not been majorly touched since. The patch has been
tested with MSVC.
