    Oh, sorry, it should have been "file dependencies", i.e., how the  
    file modification dates relate among files calling each other. When  
    using 'make', these file dependencies are written down explicitly by  
    giving the filesystem location of the files in the 'make' file, and  
    'make' then checks the file modification dates, and if a dependent  
    file has been modified, the associated action (like a compile) is  

I know how Make works, but what I don't see is how it is relevant to
the issue at hand.  We're talking about a development interface for
Bison grammars.  Why are you bringing all this stuff which relates to

    Now, the IDE's typically allows one to not having to write down these  
    file dependencies explicitly, but merely indicating the source file.  
    The IDE will then scan the source file for constructs such as  
    '#include <filename>", identifying the file with file name  
    'filename', adding it to the list of file dependencies of the source  
    file, and also doing this recursively in the included file.

It seems like you are proposing an IDE for Makefiles.  That might be
useful, but shouldn't you discuss it with the Make maintainers,
instead of the Bison maintainers?
