+- Update to GMP 6.1.2 release.
+  * Mini-GMP: Fixed a division bug, which on a machine with 64-bit
+    unsigned long affects approximately 1 out of 2^32 divisors.
+  * Mini-GMP: Fix mpz_set_str crash on inputs with a large number of
+    leading zeros. Also stricter input validation, rejecting inputs
+    with no digits.
+  * Handle more systems which require PIC code in static libraries (e.g.,
+    "hardened" Gentoo and Debian 9).
+  * Configuration for arm (-32 and -64) has been rewritten, fixing poor
+    code selection for many CPUs.
+  * Mini-GMP: Updated to the latest development version, including
+    new functions mpn_com and mpn_neg.
+- Add gmp-6.1.2-conftest.patch to fix configure test.
