	assumption that an int can hold a char *.

	* bcache.h (struct hashlink): Wrap data[] inside union with
	double to force longest alignment.
	(BCACHE_DATA): New macro to access data[].
	(BCACHE_ALIGNMENT): New macro to get offset to data[].
	* bcache.c (lookup_cache, bcache): Use BCACHE_DATA to get
 	address of cached data.  Use BCACHE_ALIGNMENT to compute
	amount of space to allocate for each hashlink struct.
