+/* 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 */
