/* Replacements for malloc and strdup with error checking. Too trivial
to be worth copyrighting :-). I did that because a lot of code used
malloc and strdup without checking for NULL pointer, and I like some
message better than a core dump... --marekm

some back-out failure recovery code. -- jfh */
