* net/loveruby/cflat/parser/Parser.jj: sizeof TYPE requires one more lookahead because EXPR of "sizeof EXPR" may have parentheses, too.  We can distinguish type and expr by 1 look ahead, because Head of type() == head of typeref() == head of typeref_base().  typeref_base has unique terminal on head.
