These changes are completely out of question.  I want to have return
values of allocation functions casted to the correct type.  Some code
you might want some day use with a C++ compiler and it also happened
several times that I changed malloc to alloca() in which can the cast is
 sometimes needed.

In this case it is not obvious that the cast isn't necessary.  Somebody
might come some day and change nl_catd to long or so.
