			The macro used is for the wrong struct. Just byte swap manually. Refreshed patches. Tested on sparc64. Signed-off-by: Rosen Penev <rosenp@gmail.com>

| 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.
