* NEWS: Document the fixes below.
* configure.ac (AC_CHECK_FUNCS_ONCE): Add siginterrupt.
* gzip.c (lstat) [!defined(HAVE_LSTAT) && !defined(lstat)]: Remove.
(SA_NOCLDSTOP, sigprocmask, sigset_t) [!defined SA_NOCLDSTOP]:
New macros.
(siginterrupt) [!defined SA_NOCLDSTOP && ! HAVE_SIGINTERRUPT]:
New macro.
(HAVE_WORKING_O_NOFOLLOW): Define to 0 if not defined.
(caught_signals, exiting_signal, remove_ofname_fd): New vars.
(remove_ofname): Remove; all uses changed to remove_ofname_fd.
(same_file, name_too_long): Remove.
(install_signal_handlers): New function. It prefers sigaction,
which is more reliable in the presence of race conditions.
Catch SIGXCPU and SIGXFSZ, too.
(main): Use it instead of installing them by hand.
(treat_file): Check for read error when closing ifd.
(treat_file, create_outfile, remove_output_file):
Avoid race conditions with signals.
(create_outfile, check_ofname): Remove most of the gorp about
working around ENAMETOOLONG deficiencies. It's obsolete now, and
anyway it had race conditions. Just rely on O_EXCL and
ENAMETOOLONG. The worst that can happen is that a file name will
be silently truncated on an obsolete machine, but no data will be lost.
(open_and_stat): Use HAVE_WORKING_O_NOFOLLOW rather than O_NOFOLLOW
to work around some O_NOFOLLOW bugs. Otherwise, fall back on
lstat only if lstat is available, as symlinks don't exist otherwise.
(open_input_file): Use O_NONBLOCK and O_NOCTTY too, to avoid
hanging gzip on special files.
(abort_gzip_signal): If sigaction is not available, ignore
signals. If we get the exiting signal, exit with ERROR status
rather than raising a signal.
* tailor.h (NO_ST_INO): Remove; no longer used now that same_file
is gone.
