mkmf and other core classes and Logger

[Iain Barnett]

While nosing around the code to the mkmf library due to another problem =
I'm having, I noticed it has it's own logging facility. I wondered why =
it doesn't use Logger since Logger is a core class too?=20

It would be useful to me while I'm debugging this other stuff to pass in =
my own Logger instance, and I'm also wondering if other core classes do =
this kind of thing and what would be the reason?

Just in case anyone knows.
