aix: handle 64bit inodes for include directories
On AIX, stat will store inodes in 32bit even when using LARGE_FILES.
If the inode is larger, it will return -1 in st_ino.
Thus, in incpath.c when comparing include directories, if several
of them have 64bit inodes, they will be considered as duplicated.
gcc/ChangeLog:
2022-01-12 Clément Chigot <clement.chigot@atos.net>
* configure.ac: Check sizeof ino_t and dev_t.
(HOST_STAT_FOR_64BIT_INODES): New AC_DEFINE to provide stat
syscall being able to handle 64bit inodes.
* config.in: Regenerate.
* configure: Regenerate.
* incpath.c (HOST_STAT_FOR_64BIT_INODES): New define.
(remove_duplicates): Use it.
libcpp/ChangeLog:
2022-01-12 Clément Chigot <clement.chigot@atos.net>
* configure.ac: Check sizeof ino_t and dev_t.
* config.in: Regenerate.
* configure: Regenerate.
* include/cpplib.h (INO_T_CPP): Change for AIX.
(DEV_T_CPP): New macro.
(struct cpp_dir): Use it.
