+/* 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
