Actually, the desirable "host" bit order depends on the application. I would suggest that there is no natural bit order in any system implementing C, because bits are not addressable in C.

However, there are times when a MSB-to-LSB order is convenient for processing, especially on big-endian machines. There are other times when a LSB-to-MSB order is more convenient. These cases may be more frequent on little-endian machines, but not restricted to them.

Would it be possible to have this be a settable parameter, without causing too much of a performance hit?
