the patch uses chk_type, but, I can't find where it is being set?

Was there a significant purpose for the added C++ comment?  If not, can you remove that?  If so, can you explain?

Last question I have is the remove-build-file primitive.  I'm wondering on a canadian cross, are the files left over on the build machine, the host machine or both the build machine and the host machine?
I see people use remote_file build delete …, file_on_host delete and remove-build-file.  Some folks even use the plain file delete.  I'd hate to guess which one you need, it hurts my brain.  I think remove-build-file is safe; just don't know if it is best.  Anyone else want to weigh in?
