I don't think this is a correct error; a.c clearly is an lvalue array;
the only error should be that this function as written is returning a
pointer to char but has the wrong return type for that. Probably the
parser handling of this extension should be calling default_conversion
before save_expr.
Also, please avoid use the empty structs and unions extension in these
testcases; it isn't necessary for them; and make those testing arrays
explicitly specify -std=gnu89.
