This causes compiler warnings which are considered fatal
by rpmlint.

In rpm build environments, the inherited signal settings may be
such that SIGPIPE is ignored. That would cause the "yes" tool
to never terminate.

".om" is not defined in groff. I haven't found it anywhere in the
docs.I believe this is a typo.

POS36-C compliance requires that setgid() is called before
setuid(), and both called after relinquishing extra groups
with setgroups().

This is required for the follow-up patch.

* configure.ac (AC_INIT): Update the version number.
* NEWS: Describe the new release.

* configure.ac: Change version number to 1.3.2.
* NEWS: Update the version number of the first section.

* gl/lib/.gitignore: Add the files generated by the pthread module
(since we now depend on that).
* bootstrap.conf (bootstrap_epilogue): Upgrade from r424 to r690
of the googletest test framework.
(buildreq): Update tool versions to the ones I'm actually using
now, since these are really the only tools I test with routinely.
(gnulib_modules): Depend on the pthread module.  Download
googletest before we run gnulib-tool (instead of in the epilogue),
so that the googletest/m4 directory is available to autoconf.
* configure.ac: Include the googletest m4 library,
unit-tests/googletest/m4.  Turn on the Automake option 'tar-ustar'
which switches the dist file format from v7 Unix to the selects
the ustar format defined by POSIX 1003.1-1988.  We need to do this
since the distribution now contains path names longer than 99
characters and the v7 format (or its consumers) cannot reliably
deal with this.  Also make explicit some of the options which in
any case are implied by the "gnits" option, since we would want to
keep them even if turning off gnits.  Add configure tests required
by the googletest framework.
* NEWS: Point out the change of tar file format used for the
distribution file.  Also mention the recent updates to googletest
and gnulib.
* unit-tests/Makefile.am: Update the build rules used to build the
googletest unit test framework.  Don't build the samples.  Build
libgtest by compiling individual source files, instead of only
libgtest-all.cc (this fixes a problem in which "make distcheck"
would otherwise fail due to dependency rule files being left
around.  Also, don't compile the sample programs.  Remove the
rules for fusing the sources.  We don't use them, and the rules
themselves are still available in googletest/Makefile.am.
* Makefile.am (ACLOCAL_AMFLAGS): Include the googletest m4
library.
(distcheck-hook): Call build-aux/check-googletest-files.sh
(this is described below).
* build-aux/check-googletest-files.sh: New script; verifies that
all the files for the "googletest" C++ Unit test framework are
included in the distribution.  This script is called from
distcheck-hook.
* .gitignore: Don't ignore build-aux

* bootstrap: Update from current gnulib.
* bootstrap.conf: Remove second (and wrong) --tests-base
argument.  Don't munge include paths in gl/tests/Makefile.am
(since now, doing that breaks the build and whatever made it
necessary before no longer does).
* src/canonify.cc: Include <config.h> before (gnulib's replacement
of) <unistd.h>.

* COPYING.bsd: Fix typo 'modifiactions'.

* src/sf-prs.cc (sccs_file::get): pass in the correct delta
information for keyword expansion instead of a blank (that is,
invalid) delta.  This fixes Savannah bug #33633.
* tests/prs/sv33633.sh: New file, test for this bug.
* tests/prs/s.sv33633.txt: Test input for the new test.
* NEWS: Mention this bug fix.

* unit-tests/Makefile.am (unit_tests): Add test_linebuf.
(test_linebuf_SOURCES): Build test_linebuf.
* unit-tests/test_linebuf.cc: New unit test file.

* tests/common/test-common (docommand): Print the test directory
and the test script as part of the label of each test, for
additional clarity and because many of them are actually not
unique.
* tests/get/sf111140.sh (label_prefix): Print qualified labels (as
for docommand).

* tests/common/real-thing: Instead of sourcing the command-names
script unconditionally, just complain if it was not already
sourced.
* tests/common/command-names: Error out if the command-names
script is sourced twice.
* tests/common/config-data: Don't source the command-names script
more than once.
* tests/common/need-prt: Likewise.

* tests/Makefile.am (test-*): Indicate the full path of each test
script.

* tests/year-2000/ext.sh: Set $TZ to GMT in order to make it
possible for implementations which convert SCCS file dates to
time_t values (but which otherwise have no bugs) to pass the
tests.
* tests/year-2000/prs-y2k.sh: Likewise.

* tests/common/command-names (admin): remove spurious space.

* configure.ac: Update version number to 1.3.2-git, to indicate
that compiled versions of this code are no longer identical to the
1.3.1 release.
* NEWS: Likewise.

* NEWS: Update version number to 1.3.1.
* configure.ac: Likewise.

* tests/prs/delta_ixg.sh: New test script for "prs -d :DI:".
* tests/prs/s.delta_ixg: New test input file for delta_ixg.sh.
* src/sf-prs.cc (print_delta): For :DI:, also print ignored
deltas.  Follow the conventions of OpenSolaris 2009.06 on the
question of how many slashes to produce.
* docs/cssc.texi (Data Keywords): Describe in more detail just how
the keyword :DI: is expanded.
(SCCS Version Differences): Explain how the expansion of :DI:
varies across implementations.
* NEWS: Mention this change.

* src/sccsfile.cc (read_delta): Accept comment lines containing
nothing at all (not even a space after the 'c').  Some historis
versions of SCCS seem to have produced these, and later versions
tolerate it.

* auxfiles/check-testfiles.sh: New script (copied from GNU
findutils e66802375963941b3b54a0e038d18eccde449e14 with some
adaptations for CSSC) for checking that we installed all the test
scripts in "make dist".
* tests/Makefile.am (dist-hook): Invoke the
auxfiles/check-testfiles.sh script.
* tests/common/Makefile.am: remove unreferenced file;
tests/Makefile.am does not recurse.
* tests/delta/Makefile.am, tests/prs/Makefile.am: Likewise.
* tests/prt/Makefile.am, tests/sact/Makefile.am: Likewise.
* tests/admin/Makefile.am, tests/unget/Makefile.am: Likewise.
* tests/val/Makefile.am, tests/what/Makefile.am: Likewise.

* tests/bsd-sccs/driver-basic.sh (h1): Modify the ordering of the
expected ouput to match OpenSolaris 2009.06.
* src/sccs.c (command): For the UNEDIT case, flush stdout before
invoking 'get' in order to pass the changed test.
* NEWS: Mention this change.

* tests/admin/init-mr.sh: Don't expect "admin -m" to interpret
a plain "-m" as meaning an empty MR list.  Distinguishing the
absence of an argument to -m requires a traditional SCCS argument
processor, and this behaviour is incompatible with modern
implementations of SCCS (for example OpenSolaris).
* tests/admin/flags.sh: Likewise.
* src/admin.cc (main): Allow an empty list of MRs to be specified
to admin, for example "admin -fv -m' '".  OpenSolaris allows
this, and we can no longer use the previous method which was to
omit the optional argument.  Elminiate doubled space in error
message.
* docs/cssc.texi (admin): document this clearly.
* NEWS: mention this change.

Remove duplicate space in "MR number(s) must be  supplied."

* src/admin.cc (main): elminiate doubled space in error message.

* tests/get/delta-summary.sh: OpenSolaris get emits the delta
summary (produced by get -L) to stdout and the SID of the gotten
delta and the number of body lines to stderr.  Expect this
behaviour.
* tests/get/delta-summary.sh (L2e): Check that the "new delta"
message also goes to stderr when we are using "get -e -L" (since
the delta summary goes to stdout).
* src/get.cc (print_id_list): New parameter, fp: the file handle
to print the IDs to.
(main): rename use_stdout to send_body_to_stdout (being a more
accurate description).
(main): add variable commentary, the file descriptor on which we
announce which delta we're getting and so forth.   This is usually
stdout, but if stdout needs to be used for something else (for
example the delta summary), commentary can be set to stderr.
* src/sf-get2.cc (get): Correct the spacing before the items in
the delta summary.  Add a trailing newline.
* NEWS: Mention this change.

* tests/sccsdiff/rap.sh: Update the tests to match the results we
actually get from sccsdiff on OpenSolaris.
* src/sccsdiff.sh.in: Update to pass the modified tests.
Specifically, use a different header for the case where -p is
specified and when it's not.
* NEWS: Mention this change.

* src/prs.cc (main): Change type of all_deltas from int to bool.
(main): Move detection of errors writing to stdout to here,
instead of sccs_file::prs().  Likewise diagnosis of the fact that
no deltas were matched.
* src/sf-prs.cc (prs): Add an output parameter, "matched", which
is set if any delta was matched (and printed).
(prs): Rewrite this method to evaluate the earlier/later cutoff in
terms of SIDs where this is necessary.  That is, avoid the
assumption that different SIDs have different timestamps.
* src/sccsfile.h (sccs_file::prs): Modify the declaration
of sccs_file::prs() to add the output parameter, "matched".
* tests/prs/sv33153.sh: New test for this bug.
* tests/prs/s.sv33153: New test input file.
* NEWS: Mention this bugfix.

* testutils/mogrify.awk: Preserve comment lines which have no
space (that is, \001Ac\n).

* testutils/uu_decode.c: avoid including unnecessary header
<stddef.h>.
* src/sf-delta.cc (add_delta): Remove doubled word in a comment.
* docs/cssc.texi (Other Variables): Remove doubled word.
(Year 2000 Summary): Likewise.
* cfg.mk: Modify spelling of a comment in order not to have a
false positive from the sc_makefile_at_at_check syntax check.
* tests/year-2000/ext.sh: Remove blank line at the end of the
file.
* tests/year-2000/prs-y2k.sh: Likewise.
* .x-sc_unmarked_diagnostics: Likewise.
* unit-tests/testwrapper.sh.in: Add final newline.
* README-hacking: Remove space-tab combinations.

* README-hacking: Update instructions detailing how to collect
gnulib (since we now use it as a submodule).
