--- Comment #19 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Vitali from comment #12) > Actually, http://en.cppreference.com/w/cpp/header seems to indicate that > when compiling as C++, complex.h should be equal to including ccomplex in a > global namespace. Maybe it used to say that, but it's correct now: <complex.h> just includes <ccomplex> and doesn't add the content to the global namespace. > It seems like the inclusion of C99 complex.h is a GNU > extension & should only be done if GNU extensions are enabled. Yes. For GCC 8 you only get C99 <complex.h> for -std=gnu++NN modes, not -std=c++NN modes. Is there still any reason to keep this bug open?
