They are too many... And this is a crud.
But as i read a standard, i understand, the rules must be transitive.
As there's stated that if there is no explicit rule, we use implicit,
thus in this case requiring to rebuild foo.c. Then we apply the same
logic and get to foo.pc to foo.c implicit rule, no?

That was what i started with:) But as there were problems i was
advised to use .pc.c rule...
