可以在全球范围内“假设新”吗？

Question

默认情况下，Make 将“触摸”提供的目标文件以“更新”。 为避免这种情况，您可以使用this option:

   -W file, --what-if=file, --new-file=file, --assume-new=file
        Pretend that the target file has just been  modified.   When  used
        with  the -n flag, this shows you what would happen if you were to
        modify that file.  Without -n, it is almost the same as running  a
        touch  command  on the given file before running make, except that
        the modification time is changed only in the imagination of  make.

Makefile 本身中是否有一个等效的设置（可能是MAKEFLAGS 选项）来为 Makefile 中定义的所有目标全局假定此选项？

Answer 1

我认为这可行：MAKEFLAGS=--assume-new=$(MAKECMDGOALS)

这样做有什么负面影响吗？
