autoconf-archive-2014.10.15 released [stable]

[Peter Simons]

A new release of the GNU Autoconf Archive is available for download.

Here are the compressed sources and GPG detached signatures[*]:

  http://ftpmirror.gnu.org/autoconf-archive/autoconf-archive-2014.10.15.tar.xz
  
http://ftpmirror.gnu.org/autoconf-archive/autoconf-archive-2014.10.15.tar.xz.sig

  http://ftpmirror.gnu.org/autoconf-archive/autoconf-archive-2014.10.15.tar.lz
  
http://ftpmirror.gnu.org/autoconf-archive/autoconf-archive-2014.10.15.tar.lz.sig

Use a mirror for higher download bandwidth:
  http://www.gnu.org/order/ftp.html

[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact.  First, be sure to download both the .sig file
and the corresponding tarball.  Then, run a command like this:

  gpg --verify autoconf-archive-2014.10.15.tar.xz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

  gpg --keyserver keys.gnupg.net --recv-keys 99089D72

and rerun the 'gpg --verify' command.

This release was bootstrapped with the following tools:
  Autoconf 2.69
  Automake 1.14.1
  Gnulib v0.1-228-gb155b06

NEWS

  A brand-new Github mirror of the Archive's Git repository is available at
  <https://github.com/peti/autoconf-archive>. That project allows developers to
  submit patches as Pull Requests instead of having to go through Savannah's
  patch tracker.

  The Archive no longer creates release tarballs compressed with gzip and
  bzip2; only tarballs compressed with xz and lzip are distributed.

  AX_LIB_POSTGRESQL: substitute CPPFLAGS rather than CFLAGS.

  AX_GCC_ARCHFLAG: Rewrite x86 support <https://savannah.gnu.org/patch/?8514>
  and extend Clang support <https://savannah.gnu.org/patch/index.php?8515>.

  AX_GCC_VAR_ATTRIBUTE: support the init_priority attribute.

  AX_PERL_MODULE_VERSION: fix a misspelled variable name. Other unfixed issues
  remain. See <https://savannah.gnu.org/patch/index.php?8507>.

  AX_BOOST_PYTHON: several issue have beeen fixed. Further details can be found
  at <https://savannah.gnu.org/patch/index.php?8540>.

  AX_HAVE_QT: Only check $PATH and qmake for Qt variables. The old logic for
  detecting Qt without $PATH or qmake was never very reliable and the last
  change to this macro broke it entirely. If the Qt variables cannot be found
  via $PATH and qmake, then it would be best to manually define them in the
  makefile.

  AX_TLS: fix quoting problem.

  AX_F90_LIBRARY: several bug fixes and improvements. Further details are at
  <https://savannah.gnu.org/patch/?8500>.

  AX_LUA: fix initialization of ac_cv_header_lua_h. Further details are at
  <https://savannah.gnu.org/patch/?8505>.

  AX_AT_CHECK_PATTERN: executes a test similar to AT_CHECK(), except that
  stdout and stderr are awk regular expressions. Further details can be found
  at <https://savannah.gnu.org/patch/?8492>.

  AX_OPENMP: prevent false negative due to -Wunused-variable.

  AX_COMPILER_VENDOR: improve detection of the CRAY compiler.

  AX_ENABLE_BUILDDIR: support absolute paths.

  AX_HAVE_QT: auto-detect Qt 5 by querying $PATH and qmake. Submitted in
  <https://savannah.gnu.org/patch/index.php?8486>.

  AX_CHECK_ENABLE_DEBUG: add an --enable-debug option which defines an
  ENABLE_DEBUG cpp variable if set. Submitted in
  <https://savannah.gnu.org/patch/index.php?8452>.

  AX_CODE_COVERAGE: new macro which contains all the necessary logic and
  Makefile rules for instrumenting a project with code coverage using lcov.
  Submitted in <https://savannah.gnu.org/patch/index.php?8451>.

  AX_LIB_HDF5: don't overwrite the CPPFLAGS variable. Submitted in
  <https://savannah.gnu.org/patch/index.php?8449>.

  AX_BOOST_BASE: fix for x32 systems. This subject probably needs more
  attention, though. See <https://savannah.gnu.org/patch/index.php?8433>.

  AX_BERKELEY_DB(_CXX): add --with-libdb option so that this macros works on
  OSX with home-brew installed version of BDB. Submitted in
  <https://savannah.gnu.org/patch/index.php?8416>.

  AX_CXX_HAVE_PLACEHOLDERS: check if std::placeholders is defined in
  <functional>. Submitted it <https://savannah.gnu.org/patch/index.php?8414>.

  AX_LIB_HDF5: add support for recognizing HDF5 built with ccache. Submitted in
  <https://savannah.gnu.org/patch/index.php?8450>.

  AX_CC_MAXOPT: Improve CPUID identification patterns as mentioned in
  patch #8514. Add ICC options added in version 11.0 (which deprecates older
  -xX style options). Add support for latest Intel performance processors
  (see #8514 for details). See <https://savannah.gnu.org/patch/index.php?8522>.

  AX_EXECINFO: new macro to test execinfo size type. Submitted in
  <https://savannah.gnu.org/patch/index.php?8525>.

  AX_CXX_VAR_PRETTYFUNC: new macro to determine the function name.

  AX_CC_MAXOPT: default to -O2 for MSVC instead of -O3.

  AX_CXX_HAVE_REFERENCE_WRAPPER, AX_CXX_HAVE_BAD_FUNCTION_CALL,
  AX_CXX_HAVE_BIND, AX_CXX_HAVE_BIT_AND, AX_CXX_HAVE_BIT_OR,
  AX_CXX_HAVE_BIT_XOR, AX_CXX_HAVE_CREF, AX_CXX_HAVE_FUNCTION,
  AX_CXX_HAVE_HASH, AX_CXX_HAVE_IS_BIND_EXPRESSION, AX_CXX_HAVE_IS_PLACEHOLDER,
  AX_CXX_HAVE_MEM_FN, AX_CXX_HAVE_REF: remove dependency on AX_CXX_NAMESPACES.

  AX_BOOST_BASE has been extended to recognize ppc64le as a lib64 architecture.
  Submitted in <https://savannah.gnu.org/patch/index.php?8473>.

  AX_PROG_FLEX has been extended to support OpenBSD.

  AX_COUNT_CPUS has been extended to support Win32 (and Win64). Further
  details are at <http://savannah.gnu.org/patch/index.php?8381>.
