Summary:
When I build RocksDB for 32bits/LITE/iOS environment, some errors like the following.
`
table/block_based_table_reader.cc:971:44: error: implicit conversion loses integer precision: 'uint64_t'
(aka 'unsigned long long') to 'size_t' (aka 'unsigned long') [-Werror,-Wshorten-64-to-32]
size_t block_size = props_block_handle.size();
~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~^~~~~~
./util/file_reader_writer.h:177:8: error: private field 'env_' is not used [-Werror,-Wunused-private-field]
Env* env_;
^
