--- Comment #5 from Roland Illig <roland.illig at gmx dot de> ---
From fortran/intrinsic.c:
gfc_warning_now (OPT_Wintrinsics_std, "The intrinsic %qs at %L is not "
"included in the selected standard but %s and %qs
will"
" be treated as if declared EXTERNAL. Use an"
" appropriate %<-std=%>* option or define"
" %<-fall-intrinsics%> to allow this intrinsic.",
sym->name, &loc, symstd, sym->name);
After the "-std=".
