* configure.in, libmisc/copydir.c: futimes() and lutimes() are not
standard. Check if they are implemented before using them. Do not
set the time of links if lutimes() does not exist, and use
utimes() as a replacement for futimes().
prototypes.
* libmisc/copydir.c: Use a size_t for the length of strings.
* libmisc/copydir.c: Cast the return value of malloc().
* libmisc/copydir.c: The size argument of write() is a size_t.
followed by rmdir to remove the directory itself, delete also the
root directory in remove_tree.
* src/userdel.c, src/usermod.c: Do not call rmdir after
remove_tree.
with post increments (x++), use of integers as booleans, and
explicitly mark blocks with brackets.
* libmisc/copydir.c: Likewise.
* libmisc/fields.c: Add comments.
* libmisc/copydir.c: Mark function whose return value is not
checked as such.
* libmisc/copydir.c (remove_tree): Make sure unlink is successful
when removing files.
Files with no license use the default 3-clauses BSD license. The copyright
were mostly not recorded; they were updated according to the Changelog.
"Julianne Frances Haugh and contributors" changed to "copyright holders
and contributors".
gid parameters can be set to -1 to indicate that the original
owners must be kept. Change the types from uid_t/gid_t to a
long int (signed).
* libmisc/copydir.c: Change the copy_entry(), copy_dir(),
copy_symlink(), copy_special(), and copy_file() prototypes
accordingly.
* lib/prototypes.h: Add the parameters' name for the
libmisc/copydir.c functions.
* libmisc/copydir.c: Split copy_tree() in more maintainable functions:
copy_entry(), copy_dir(), copy_symlink(), copy_hardlink(),
copy_special(), and copy_file().
* libmisc/copydir.c: -1 is used to indicate an error, directly set err
to -1, instead of incrementing it, and checking if not nul at the
end.
* NEWS: Document that usermod will now preserve user's file modification
and access time.
* libmisc/copydir.c: Preserve the access and modification time of copied
files. This is important for usermod. This will also impact useradd, for
the skeleton files, but this is not important.
* libmisc/copydir.c: Stop and return an error if a file could not be
closed after during a copy.
