The difference between sys/bitstring.h and the package I propose is that
bitstring.h implements a bit array within one unit of data storage (unsigned
char, 1 byte, 8 bits), while my package uses an array of units (array of
unsigned long integers, usually 32 or 64 bits EACH). This means that BSD's bit
array can't be longer that 8 bits, while mine is limited by memory size only.

Oh, yes, you are right. I was able to reproduce this problem. The name of the
header guard needs to be changed. Thank you very much for pointing it out.
