* m4/stddef_h.m4 (gl_STDDEF_H): Set and substitute HAVE_C_UNREACHABLE. Don't test for unreachable in <stddef.h> in C++. Set GL_GENERATE_STDDEF_H to true always. * lib/stddef.in.h (gl_unreachable): Renamed from _gl_unreachable. Test HAVE_C_UNREACHABLE. (unreachable): Don't define in C++ mode. Don't define if HAVE_C_UNREACHABLE is 1. * modules/stddef-h (Makefile.am): Substitute HAVE_C_UNREACHABLE. * tests/test-stddef-h.c (test_unreachable_optimization, test_unreachable_noreturn): Don't define in C++ mode. (test_gl_unreachable_optimization, test_gl_unreachable_noreturn): New functions. * tests/test-stddef-h-c++3.cc (test_cxx_unreachable_1): Test gl_unreachable instead of unreachable. * lib/error.in.h (__gl_error_call1): Use gl_unreachable instead of unreachable.
