it's not exactly a bit array (arbitrary number of bits implemented eg.
as char array), it's only one int (with bit flags)

this is portable (a possible caveat is that some bit operations on
negative values are implementation defined by c89 (eg. -1 >> 1) so
unsigned int is recommended in those cases)
