-/* The size of memory objects is often computed through expressions of
-   type size_t. Example:
-      void* p = malloc (header_size + n * element_size).
-   These computations can lead to overflow.  When this happens, malloc()
-   returns a piece of memory that is way too small, and the program then
-   crashes while attempting to fill the memory.
-   To avoid this, the functions and macros in this file check for overflow.
-   The convention is that SIZE_MAX represents overflow.
-   malloc (SIZE_MAX) is not guaranteed to fail -- think of a malloc
-   implementation that uses mmap --, it's recommended to use size_overflow_p()
-   or size_in_bounds_p() before invoking malloc().
-   The example thus becomes:
-      size_t size = xsum (header_size, xtimes (n, element_size));
-      void *p = (size_in_bounds_p (size) ? malloc (size) : NULL);
