 * power-of-2 numbers of bytes).  Additionally this fixes compilers that rewrite
 * structure assignments and ANSI C memcpy calls to be in-line instructions
 * that happen to require alignment.
 *
 * uintptr_t --
 * Unsigned type that's the same size as a pointer.  There are places where
 * DB modifies pointers by discarding the bottom bits to guarantee alignment.
 * We can't use uintmax_t, it may be larger than the pointer, and compilers
 * get upset about that.  So far we haven't run on any machine where there's
