9 Portability problems fixed by Gnulib:
12 Some platforms fail to detect trailing slash on non-directories, as in
13 @code{chown("link-to-file/",uid,gid)}:
14 FreeBSD 7.2, AIX 7.1, Solaris 9.
16 Some platforms fail to update the change time when at least one
17 argument was not @minus{}1, but no ownership changes resulted:
20 When passed an argument of @minus{}1, some implementations really set the owner
21 user/group id of the file to this value, rather than leaving that id of the
24 When applied to a symbolic link, some implementations don't dereference
25 the symlink, i.e.@: they behave like @code{lchown}.
27 This function is missing on some platforms; however, the replacement
28 always fails with @code{ENOSYS}:
