* `#' in a line of a makefile starts a "comment". It and the rest of the line are ignored, except that a trailing backslash not escaped by another backslash will continue the comment across multiple lines. A line containing just a comment (with perhaps spaces before it) is effectively blank, and is ignored. If you want a literal `#', escape it with a backslash (e.g., `\#'). Comments may appear on any line in the makefile, although they are treated specially in certain situations.
注释行以#开头。#符号和之后的本行字符将被忽略。
如果尾部有一个\，而不是\\的话，就可与形成多行注释。
一行中仅仅包含注释在效果上实际就是一个空白，将被make 忽略。
如果你想输入'#',应当使用反斜线(\#)。
注释可以出现在makefile的任何一行，但是有时候在特殊的情况下，他们也会被特殊处理。
