c++14 instead of 11 now.

     Type:  defect    |     Status:  new
 Priority:  Normal    |  Milestone:
Component:  ports     |    Version:  2.8.1
 Keywords:            |       Port:  postgis3 protobuf-c
----------------------+---------------------------------
 * Cleaned and ran `sudo port install postgis3` again: Failed again.
 * Checked the [https://trac.macports.org/wiki/ProblemHotlist problem
 hotlist]: Not listed.
 *
 [https://trac.macports.org/search?q=postgis3&noquickjump=1&portsummarysearch=on
 Searched] for existing tickets: #67339 is ''similar'' but looks to be a
 missing directory, not `CXX_STANDARD` related.
 * Problem is specific to compilation.
 * Problem is not related to `port upgrade`.

 This seems to be the relevant bit from the log file:

 Assuming `absl` is actually [https://github.com/abseil/abseil-cpp abseil],
 then there's a [https://github.com/abseil/abseil-
 cpp/releases/tag/20230125.3 recent release note] indicating it now
 requires c++14. Possibly [https://github.com/macports/macports-
 ports/blob/4cf20f01/devel/protobuf-c/Portfile#L36 protobuf-c], which is a
 dependency of postgis3 and has `compiler.cxx_standard 2011` in its
 Portfile?

 This must be a second-level dependency though, because the
 [https://github.com/macports/macports-
 ports/blob/master/databases/postgis3/Portfile Postgis3 Portfile] doesn't
 contain any reference to `c++11`.
