How about

-			if (atol(p->type->size) == 1)
+			if (strcmp(p->type->size, "1") == 0)

?  I've not actually tested, but this should catch the cases the
warning is meant to catch while not complaining about any of the
examples you give.  I'm not sure if leading/trailing spaces
would fool it (i.e., "char foo[ 1 ];").  But even if they do,
that doesn't seem disastrous.
