Looks like the real problem is not that __FILE__ doesn't resolve to a
full path--that's more of a solution.

The real discrepancy that bit me was, with the following tree:


./in_root.rb:

Dir.chdir 'subdir'
require 'in_subdir'

subdir/
  in_subdir.rb:
  puts File.join(File.dirname(__FILE__), 'config', 'boot')

on windows:

C:\dev\test>ruby in_root.rb
./config/boot

on linux:

$ ruby in_root.rb
/home/rdp/dev/test/subdir/config/boot

Which tripped me up.
Is this difference expected?

Thanks!
