STR:
  1. Create a new external makefile project, containing some code
     that includes a C++11 standard library header such as <chrono>,
     and uses C++11 library features defined in it (such as 
     std::chrono::seconds).
  2. Initially, std::chrono::seconds is not resolved. This is fine,
     as the project is not yet configured to use C++11.
  3. Configure the project to use C++11, by going to Project Properties
     --> C/C++ General --> Preprocessor Paths, Includes, Macros, etc.
     --> Providers --> CDT GCC Built-in Settings Provider, and adding
     "-std=c++11" to the "command to get compiler specs".
  4. Press "Apply". This triggers a fairly short reindex.
  5. After the reindex, std::chrono::seconds is still unresolved.
  6. Now, trigger another reindex via Project -> Index -> Rebuild.
  7. Now, std::chrono::seconds is resolved.

Clearly, the reindex done by step (4) isn't a full reindex in some way. I think it should be, so that an subsequent explicit reindex isn't required.
