/* Issues:
1. putenv must not use setenv since the string provided by the user
must be used, not a copy
2. a common function should determine the place where to insert the
new entry and if necessary take care of extending the array
3. It must be kept track of whether an entry was inserted via putenv
or setenv. In the former case the entry must not be put into
the search tree since removing it could mean it will not be
available anymore (e.g., when allocated on the stack)
To handle this an array parallel to the __environ array must specify
whether the entry was added via putenv or not
