(gfc_cpp_register_include_paths): Make static, set pfile's warn_missing_include_dirs and move before caller. (gfc_cpp_init_cb): New, cb code moved from ... (gfc_cpp_init_0): ... here. (gfc_cpp_post_options): Call gfc_cpp_init_cb. (cb_cpp_diagnostic_cpp_option): New. As implemented in c-family to match CppReason flags to -W... names. (cb_cpp_diagnostic): Use it to replace single special case. * cpp.h (gfc_cpp_register_include_paths): Remove as now static. * gfortran.h (gfc_check_include_dirs): New prototype. (gfc_add_include_path): Add new bool arg. * options.c (gfc_init_options): Don't set -Wmissing-include-dirs. (gfc_post_options): Set it here after commandline processing. Call gfc_add_include_path with defer_warn=false. (gfc_handle_option): Call it with defer_warn=true. * scanner.c (gfc_do_check_include_dir, gfc_do_check_include_dirs, gfc_check_include_dirs): New. Diagnostic moved from ... (add_path_to_list): ... here, which came before cmdline processing. Take additional bool defer_warn argument. (gfc_add_include_path): Take additional defer_warn arg. * scanner.h (struct gfc_directorylist): Reorder for alignment issues, add new 'bool warn'. libgfortran/ChangeLog: PR fortran/55534 * configure.ac (AM_FCFLAGS): Add -Wno-missing-include-dirs. * configure: Regenerate. libgomp/ChangeLog: PR fortran/55534 * testsuite/libgomp.fortran/fortran.exp: Add -Wno-missing-include-dirs to ALWAYS_CFLAGS. * testsuite/libgomp.oacc-fortran/fortran.exp: Likewise. gcc/testsuite/ChangeLog: * gfortran.dg/include_6.f90: Change dg-error to dg-warning and update pattern. * gfortran.dg/include_14.f90: New test. * gfortran.dg/include_15.f90: New test. * gfortran.dg/include_16.f90: New test. * gfortran.dg/include_17.f90: New test. * gfortran.dg/include_18.f90: New test. * gfortran.dg/include_19.f90: New test. * gfortran.dg/include_20.f90: New test. * gfortran.dg/include_21.f90: New test.
