This won't be necessary, because the POSIX libraries already include
the equivalent function:
POSIX_Process_Environment.Environment_Value_Of
      (Name      : POSIX.POSIX_String;
       Undefined : POSIX.POSIX_String := "")

Presumably the reaosn David Wheeler includes his own binding to
Getenv is so that he doesn't force you to install the POSIX
libraries.

Since there is no so much C, Java etc out there, you can only benefit
by pulling you head out of the sand.

If you need it, do it!

Is there an XML paser written in Java?

That would not be the correct place for getenv, IMO.
