/usr/ccs/bin has been replaced by a symlink to /usr/bin since at least
Solaris 11.3, so there's no reason to use that path any longer.

This patch removes all references to it.

Tested on i386-pc-solaris2.11.

	* configure.ac (md_exec_prefix): Don't set on Solaris.
	* configure: Regenerate.

	contrib:
	* make_sunver.pl ($elfdump): Remove ccs from path.

	gcc:
	* config/sol2.h (MD_EXEC_PREFIX): Remove.

	libstdc++-v3:
	* scripts/extract_symvers.pl: Remove ccs from elfdump path.

On Windows there is no API to get the current time zone as IANA name,
instead Windows has its own zones. But there exists a mapping provided
by the Unicode Consortium. This patch adds a script to convert the XML
file with the mapping to a lookup table and adds a Windows code path to
use that mapping.

libstdc++-v3/Changelog:

	Implement std::chrono::current_zone() for Windows

	PR libstdc++/108409
	* scripts/gen_windows_zones_map.py: New file, generates
	windows_zones-map.h.
	* src/c++20/windows_zones-map.h: New file, contains the look up
	table.
	* src/c++20/tzdb.cc (tzdb::current_zone): Add Windows code path.

This script claims that wchar_t tests are filtered out if the toolchain
being tested doesn't support it.  That doesn't seem to have been true
since r0-68039-ga72c74a1dee345 in 2005.

libstdc++-v3/ChangeLog:

	* scripts/create_testsuite_files: Remove incorrect comment about
	filtering out wchar_t tests.

    libstdc++: correct symbol version of typeinfo for bfloat16_t on RISC-V

broke the libstdc++-abi/abi_check test on Solaris: the log shows

1 incompatible symbols
0
Argument "{CXXABI_1.3.15}" isn't numeric in numeric eq (==) at /vol/gcc/src/hg/master/local/libstdc++-v3/scripts/extract_symvers.pl line 129.
version status: incompatible
type: uncategorized
status: added

The problem has two parts:

* The patch above introduced a new version in libstdc++.so,
  CXXABI_1.3.16, which everywhere but on RISC-V contains no symbols (a
  weak version).  This is the first time this happened in libstdc++.

* Solaris uses scripts/extract_symvers.pl to determine the version info.
  The script currently chokes on the pvs output for weak versions:

  libstdc++.so.6.0.34 -	CXXABI_1.3.16 [WEAK]: {CXXABI_1.3.15};

  instead of

  libstdc++.so.6.0.34 -	CXXABI_1.3.16: {CXXABI_1.3.15};

While this patch hardens the script to cope with weak versions, there's
no reason to introduce them in the first place.  So the new version is
only created on __riscv.

Tested on i386-pc-solaris2.11, sparc-sun-solaris2.11, and
x86_64-pc-linux-gnu.

	libstdc++-v3:
	PR libstdc++/118701
	* config/abi/pre/gnu.ver (CXXABI_1.3.16): Move __riscv guard
	around version.
	* scripts/extract_symvers.pl: Allow for weak versions.
	* testsuite/util/testsuite_abi.cc (check_version): Wrap
	CXXABI_1.3.16 in __riscv.

The results of 'make check-performance' are appended to the .sum file,
with no indication where one set of results ends and the next begins. We
could just remove the file when starting a new run, but appending makes
it a little easier to compare with previous runs, without having to copy
and store old files.

This adds a header containing a timestamp to the file when starting a
new run.

libstdc++-v3/ChangeLog:

	* scripts/check_performance: Add timestamp to output file at
	start of run.

This should be run on a release branch after branching from trunk.
Various links and references to trunk in the docs will be updated to
refer to the new release branch.

libstdc++-v3/ChangeLog:

	* scripts/update_release_branch.sh: New file.

The Doxygen-generated man pages for some new types need to be renamed to
use '::' instead of '_' in the filenames.

libstdc++-v3/ChangeLog:

	* scripts/run_doxygen: Rename man pages for nested types.

Doxygen switched from \fC to \fR in its man page output:
https://github.com/doxygen/doxygen/pull/10497

This breaks our script that expects \fC so change the regaulr expression
to work with either style.

libstdc++-v3/ChangeLog:

	* scripts/run_doxygen: Adjust sed pattern to match '\fR' for
	new man output that Doxygen 1.10 generates.

These scripts both print "generated by $file, do not edit" header but
one of them prints the wrong filename. Use the built-in __file__
attribute to ensure it's correct.

contrib/ChangeLog:

	* unicode/gen_libstdcxx_unicode_data.py: Fix header of generated
	file to name the correct script.

libstdc++-v3/ChangeLog:

	* include/bits/text_encoding-data.h: Regenerate.
	* include/bits/unicode-data.h: Regenerate.
	* scripts/gen_text_encoding_data.py: Fix header of generated
	file to name the correct script.
