Dear Maintainer,

  changes made:

  Define "active_directory".

  Define a name for a constant number and
substitute the name for that number.

  Improve prototypes by adding declarations to the argument list.

  Use the "n"-version of "sprintf" and "vsprintf".

  Create a new directory "active_directory" if not existent.

  Use "invalid" instead of "illegal", see GNU standard.

  Add text to some messages.

  Remove the "NEED_STRDUP" configuration constant and the associated
code for the definition of "strdup".
