Is there anywhere a precise makefile grammar definition? Or at least some common subset since I guess that there are some flavors. Such a grammar that could be used for writing a parser.

GNU Make 手册 似乎没有那么精确.根据该文档为 makefile 编写解析器需要一些猜测和反复试验.

GNU Make manual doesn't seem to be that precise. It would require some guessing and trial-and-error to write a parser for makefile based on that document.
