[boost] [dynamic_bitset] Append byte to the less significant end

Hi, Here is my problem: i am using boost::dynamic_bitset and I would like to append a byte to the bitset. The idea is the following: 1) read a byte (represented as an unsigned char) 2) append the byte to the bitset 3) repeat these steps until there is no more data to read The current "append" in the API appends a byte to the most significant end. I would like to actually append the byte to the less significant end. The only solution that I have found so far is to concatenate two bitsets: http://pastebin.com/cguqaMgS I am not sure this is a very efficient way. Do you have any other suggestions? Thank you for your help and Merry Christmas. Romain
