So there are some existing cases of asking permission using "may".

True, but essentially the same ambiguity is present for "can."
"Joe can open the door during the meeting" could mean "Joe is able to
open the door (e.g., he has the keys)" or "from time to time, Joe will
open the door during the meeting (e.g., it has been known to happen)."
But I agree that it doesn't seem to be used that way in gcc.
