From e436e40b57125472ba732a5d39407ff52f008f52 Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Thu, 25 Dec 2014 18:52:00 +0100 Subject: [PATCH] configure: add check for bswap_64 include/f2fs_fs.h checks the HAVE_BSWAP_64 conidtional, but configure nevers checks for it. Add a check that the function is indeed declared, and fix the variable name to match the naming scheme of autoconf (and not those of WAF like is used by samba), and adapt the check as suggested in the autoconf manual.
