> Why do you need XFREE while FREE exists?

xmalloc() checks for null return from malloc, and dies if so.
xrealloc() checks for you passing a null, and calls malloc() if so.
xfree() checks for you passing a null, and ignores it if so.

Some systems have broken malloc/realloc/free, so the x*() versions fix
them.  This is common practice under Unix.
