Hi Earnie!

Right, to express myself more clearly, I don't think it is unfriendly to
require 'file' as such. I just think it is over on the unfriendly side to
/silently/ require it and break in mysterious ways when it is missing.
Especially so when it is so easy to create a Cygwin installation that
lacks it. 'file' is not part of the Cygwin base install, and few packages
require it, Libtool, Cygport and a couple of others. But nothing you
generally need to build things like make, binutils or gcc require 'file'
so it is very easy to overlook it.
