* os9kread.c (os9k_process_one_symbol): Note nonportable
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.
