- variable in the environment is added, deleted, or changes
- its value. It is meant to be used by functions that depend
- on values of environment variables, but don't want to call
- `getenv' unnecessarily (example: `__use_lfn').
-
- To use this feature, define a static variable that is
- initialized to zero, and compare its value with the value of
- `__environ_changed': if they differ, you should call `getenv'
- (and record the last value of `__environ_changed' you've seen). */
