[Rd] Rbuildignore question

[Terry Therneau]

I'm touching up changes to rpart and have a question with .Rbuildignore.  Here is my file

tmt1014% more .Rbuildignore

\.hg
src/print_tree.c


  The source code included a module "print_tree.c", used for dubugging.  Commented
out calls to can be found here and there.  I want to leave it in the source tree
even though no submitted copy of rpart will use it.

  Even with the ignore line above, R CMD check still compiles it, and gives a "bad
boy" NOTE about use of printf.  Can I/ should I/ how do I get rid of this?
