I think the depend tag is very interesting.  Because it is very
different to usual pre-scanning approach.  I think using compiler
knowledge is correct way.

automake people also have some idea.

Also, the following paper presents Makefile is not required to extract
dependeices if shell history is available.

While old good make style precious dependency with some scanning
system is practical, but not exciting for me.  If I design make like
tool, I will design Makefile as shell script (or other procedual
language) and extract dependencies from it.
