-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.
