On Windows, the environment variable NUMBER_OF_PROCESSORS has special meaning. Unfortunately, you can get different answers, depending on whether you are enumerating all environment variables or querying a specific variable. This was causing the src/test/ui/env-vars.rs test to fail on machines with more than 64 processors when run on Windows.
