See also #12173, upgrading FLINT to 2.3. Does the qsieve there do what we need?

---

Also note #14202, which is orthogonal but also about qsieve, so it should be pointed out.

Puttins as need-info, since there's a pending question: does flint 2.3 make it possible to get flintqs out?

I think FLINT 2.3 provides a quadratic sieve implementation but only for two limbs integers.
See:

• https://github.com/wbhart/flint2/blob/trunk/qsieve/doc/qsieve.txt
  So I guess the answer is currently no.
  We'll have to wait until Bill or someone else ports the old code.

(FLINT 1.6 included a quadratic sieve to build as a separate executable, see:

• http://www.flintlib.org/flint-1.6.pdf, section 18, page 64;
  as did FLINT 1.5.2 (latest version included in Sage):
• http://www.flintlib.org/flint-1.5.2.pdf, section 14, page 57.)
