+/* 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 */
