Warning in master in C++11 mode

[Jean-Marc Lasgouttes]

Hi,

I get this warning when compiling in C++11 mode :

../../master/src/insets/InsetIndex.cpp: In member function ‘virtual void 
lyx::InsetIndex::docbook(lyx::XMLStream&, const lyx::OutputParams&) const’:
../../master/src/insets/InsetIndex.cpp:376:6: warning: init-statement in 
selection statements only available with ‘-std=c++17’ or ‘-std=gnu++17’
   376 |  if (const vector<docstring> potential_terms = 
getSubentriesAsText(runparams); !potential_terms.empty()) {
       |      ^~~~~


Thibaut, can I leave that to you ?
