It would be better to include xalloc.h in sunders.h only.

^^^^^^^^

it means that you have to use:
#define XALLOC_EXIT_CODE EX_SYSERR
#include "xalloc.h"
to keep it backwardly compatible.

The reason I kept this silly function was because gcc complains about
freeing const char * variables, which is quite correct. What do you
think about un consitifying them and getting rid of die_if_null()?
