Comment (by ballapete):

 `gpgme` is compiled like this:

 {{{
 /bin/sh ../../../libtool  --tag=CXX   --mode=compile
 /opt/local/bin/g++-mp-7 -std=c++11 -DHAVE_CONFIG_H -I. -I../../../conf
 -I../../../src -fvisibility=hidden -I/opt/local/include
 -I/opt/local/include -DBUILDING_GPGMEPP -Wsuggest-override -Wzero-as-null-
 pointer-constant -I/opt/local/include  -pipe -Os -std=c++17
 -D_GLIBCXX_USE_CXX11_ABI=0 -arch ppc -MT context_vanilla.lo -MD -MP -MF
 .deps/context_vanilla.Tpo -c -o context_vanilla.lo context_vanilla.cpp
 }}}

 So `GCC 7.5` understands a six or seven years old standard?
