#992: Failed configure on Ubuntu 16.04 (GCC 5.4.0 found unable to do C++11)

     Type:  defect      |     Status:  new
 Priority:  major       |  Milestone:
Component:  Default     |    Version:  master
 Severity:  Unassigned  |   Keywords:
------------------------+--------------------------
 On an Ubuntu 16.40 system, having
 gcc (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0

 The ./configure step fails:
 {{{
 checking whether g++ supports C++11 features by default... no
 checking whether g++ supports C++11 features with -std=c++11... no
 checking whether g++ supports C++11 features with -std=c++0x... no
 checking whether g++ supports C++11 features with +std=c++11... no
 checking whether g++ supports C++11 features with -h std=c++11... no
 configure: error: *** A compiler with support for C++11 language features
 is required.
 }}}

 Note that -std=c++11 switch _is_ supported by that compiler version, so I
 dunno why the configure test fails.
