From 932847e0c3df8f6ee3dc4478f1ef0728926d9544 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Wed, 22 Nov 2017 20:21:04 +0100 Subject: gmputil: turn mpz_printf into mpz_vfprintf to restore --with-mini-gmp 2535ba7006f2 ("src: get rid of printf") uses gmp_vfprintf() which doesn't exists in mini-gmp.c, this breaks compilation with --mini-gmp. This patch implements poor man's gmp_vfprintf that takes one single argument which is what we need.
