Comment (by kencu):

 This is to confirm that the patch in
 <https://trac.macports.org/ticket/54949#comment:7> allows gcc5 to build
 through to completion, and it appears to work as 5.4.0 did before, on
 highsierra.

 That is a trivial patch to apparently get the same functionality we had
 before.

 The update to 5.5.0 seems near; whether there is a need to install the RC
 version, or wait for the official 5.5.0 release I leave up to Ryan etc.

 The additions to the Port to bring in the java stuff from gcc4.9 and other
 changes by nortcele are noted, and would need some further review.
