Error in project makefile format
PWB is unable to read the project makefile as a PWB makefile.
The file is not a PWB makefile, or it has been altered in such a
way that PWB cannot recognize it as a PWB makefile.
If you have edited the file or it is a makefile that was not
created by PWB:
■ Turn on the Use as a Non-PWB Makefile check box in the
Open Project dialog box when you open the project.
OR
■ Use the Meta form of the Project function.
