If you compile with -I.../include/json, then the standard library might accidentally include a JSON header. (In this case, according to asuter, it was features.h.)

The parent directory is a kind of "namespace" for header files. That's why a good practice for any library with headers like incdir/foo/bar.h is -Iincdir and #include .
