189	A C version of a very very good 64-bit RNG is given below.
190	You should be able to adapt it to your particular needs.
191
192	It is based on the complimentary-multiple-with-carry
193	sequence
194	x(n)=a*x(n-4)+carry mod 2^64-1,
195	which works as follows:
196	Assume a certain multiplier 'a' and a base 'b'.
197	Given a current x value and a current carry 'c',
198	form: t=a*x+c
199	Then the new carry is c=floor(t/b)
200	and the new x value is x = b-1-(t mod b).
201
202
203	Ordinarily, for 32-bit mwc or cmwc sequences, the
204	value t=a*x+c can be formed in 64 bits, then the new c
205	is the top and the new x the bottom 32 bits (with a little
206	fiddling when b=2^32-1 and cmwc rather than mwc.)
207
208
209	To generate 64-bit x's, it is difficult to form
210	t=a*x+c in 128 bits then get the new c and new x
211	from the top and bottom halves.
212	But if 'a' has a special form, for example,
213	a=2^62+2^47+2 and b=2^64-1, then the new c and
214	the new x can be formed with shifts, tests and +/-'s,
215	again with a little fiddling because b=2^64-1 rather
216	than 2^64. (The latter is not an optimal choice because,
217	being a square, it cannot be a primitive root of the
218	prime a*b^k+1, where 'k' is the 'lag':
219	x(n)=a*x(n-k)+carry mod b.)
220	But the multiplier a=2^62+2^47+2 makes a*b^4+1 a prime for
221	which b=2^64-1 is a primitive root, and getting the new x and
222	new c can be done with arithmetic on integers the size of x.
