same-inode: port to MinGW Here st_ino is always 0, so change the definition of SAME_INODE so that 1 means the two files are the same, 0 with st_ino != 0 means they differ, and 0 with st_ino == 0 means we don’t know. Problem reported by Bruno Haible (Bug#25146). * doc/posix-headers/sys_stat.texi (sys/stat.h): Update. * lib/same-inode.h (SAME_INODE): Return 0 on MinGW.
