* c-typeck.c (convert_for_assignment): Bring back conversion to union without a cast, undoing the Jan 16 change, but with the following differences: * The union must have the transparent_union attribute. * The conversion must be for a function argument. * Warn consistently about such conversions if pedantic. * Do not warn about an assignment incompatibility for one union member if another union member is compatible with no warning.
