--- Comment #3 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
The check has been introduced at revision r141931 and is now
/* We are told not to check dependencies.
We do it, however, and issue a warning in case we find
one.
If a dependency is found in the case
elemental == ELEM_CHECK_VARIABLE, we will generate
a temporary, so we don't need to bother the user. */
gfc_warning (0, "INTENT(%s) actual argument at %L might "
"interfere with actual argument at %L.",
intent == INTENT_OUT ? "OUT" : "INOUT",
&var->where, &expr->where);
The warning is unconditional, but it should be easy to replace the 9 with some
suitable option.
