我正在尝试注释一个flex程序，但是编译器给了我这些错误：
chef.l：21：坏字符：/ cook.l：21：坏字符：* Chef.l：21：启动条件INW声明了两次Chef.l：21：坏字符：：
我该如何解决此问题？

* The WC definition matches any word character, and the NW definition matches

* and NIW (not in word). The first rule passes TeX commands without change.

缩进您的评论。 （除非它们在代码块中。）
Flex将第一个字符不是空格的行视为定义（在第一部分）或规则（在第二部分）。
缩进的行直接写入生成的扫描仪。如果他们是评论，那会没事的。
定义和大多数其他flex声明不能包含注释。
