Overview
– This file contains all sorts of little compatibility hacks that we’ve had to introduce over the years. Quarantining them into one file helps us know when we can get rid of them.
Ruby 1.9.x has introduced some things that are awkward, and we need to support them, so we define some constants to use later. ++

.find_latest_files(glob, check_load_path = true) ⇒ Object
Returns a list of paths matching glob
from the latest gems that can be used by a gem to pick up features from other gems. For example:
Gem.find_latest_files('rdoc/discover').each do |path| load path end
if check_load_path
is true (the default), then find_latest_files also searches $LOAD_PATH for files as well as gems.
Unlike find_files, find_latest_files will return only files from the latest version of a gem.

You can run this automatically when rubygems starts. To enable, set the RUBYGEMS_GEMDEPS
environment variable to either the path of your Gemfile or “-” to auto-discover in parent directories.
NOTE: Enabling automatic discovery on multiuser systems can lead to execution of arbitrary code when used from directories outside your control.
