[boost] Boost.Endian - endian_buffer requirements

Hi, I wanted to put an Int wrapper inside a endian_buffer and I have some compiler errors depending on whether it is aligned ort not. http://melpon.org/wandbox/permlink/k52wH2A7yagL2vMP I was expecting that the endian_buffer would make abstraction of the wrapped type and consider it just as a sequence of bytes, but it seems that it instead works only for some builtin integral. Am I missing something? Was this restriction intended? Could this restriction be removed and if yes, how? Best, Vicente
