+From: Sergei Trofimovich <slyfox@gentoo.org>
+Date: Sun, 26 Jan 2020 18:35:13 +0000
+Subject: [PATCH] squashfs-tools: fix build failure against gcc-10
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On gcc-10 (and gcc-9 -fno-common) build fails as:
+
+```
+cc ... -o mksquashfs
+ld: read_fs.o:(.bss+0x0):
+  multiple definition of `fwriter_buffer'; mksquashfs.o:(.bss+0x400c90): first defined here
+ld: read_fs.o:(.bss+0x8):
+  multiple definition of `bwriter_buffer'; mksquashfs.o:(.bss+0x400c98): first defined here
+```
+
+gcc-10 will change the default from -fcommon to fno-common:
+https://gcc.gnu.org/PR85678.
+
+The error also happens if CFLAGS=-fno-common passed explicitly.
