[boost] [dynamic_bitset] Endianess and Adaption Vs Copying

I've noticed that the dynamic_bitset seems to have endian issues. For masking out the ith bit in a block, it uses 1 shifted left by i. As a result, the bits are not consecutive. For example if the block_type is uint8_t, and we have 16 bits in the bitset, then bits are numbered: 00 01 02 03 04 05 06 07 15 14 13 12 11 10 09 08 in memory. That doesn't seem right---7th and 8th bits should be adjacent. Does anyone have suggestions for controlling this? Second, has anyone adapted dynamic_bitset to be an adaptor for an existing memory range to avoid copying? Thanks! Joel
