Who not create abstract framework for work with bitmask more then 64bits
size? 
similar this:

#define_bitmask(name,size)	char name[(size/8)+1];
#define set_bit(bimask,no)	{ bitmask[(no/8)] |= 1<<(no%8); }
#define clr_bit(bitmask,no)		{ bitmask[(no/8)] &= ~(1<<(no%8)); }
static inline isset_bit(char *bitmask, no) {
	return bitmask[(no/8)] & 1<<(no%8);
}
