/* 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
Yeh, but. Remember that bailing out might leave the system in some
bizarre state. You really want to put in error checking, then add
some back-out failure recovery code. -- jfh */
