1417
1418 Defaults for the options are specified in brackets.
1419
1420 Configuration:
1421   -h, --help              display this help and exit
1422       --help=short        display options specific to this package
1423       --help=recursive    display the short help of all the included packages
1424   -V, --version           display version information and exit
1425   -q, --quiet, --silent   do not print \`checking ...' messages
1426       --cache-file=FILE   cache test results in FILE [disabled]
1427   -C, --config-cache      alias for \`--cache-file=config.cache'
1428   -n, --no-create         do not create output files
1429       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1430
1431 Installation directories:
1432   --prefix=PREFIX         install architecture-independent files in PREFIX
1433                           [$ac_default_prefix]
1434   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1435                           [PREFIX]
1436
1437 By default, \`make install' will install all the files in
1438 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1439 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1440 for instance \`--prefix=\$HOME'.
1441
1442 For better control, use the options below.

1519 Some influential environment variables:
1520   CC          C compiler command
1521   CFLAGS      C compiler flags
1522   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1523               nonstandard directory <lib dir>
1524   LIBS        libraries to pass to the linker, e.g. -l<library>
1525   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1526               you have headers in a nonstandard directory <include dir>
1527   CPP         C preprocessor
1528   CXX         C++ compiler command
1529   CXXFLAGS    C++ compiler flags
1530   YACC        The `Yet Another Compiler Compiler' implementation to use.
1531               Defaults to the first program found out of: `bison -y', `byacc',
1532               `yacc'.
1533   YFLAGS      The list of arguments that will be passed by default to $YACC.
1534               This script will default YFLAGS to the empty string to avoid a
1535               default value of `-d' given by some make applications.
1536   CXXCPP      C++ preprocessor
1537
1538 Use these variables to override the choices made by `configure' or to help
1539 it to find libraries and programs with nonstandard names/locations.

3381 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
3382
3383 Please tell bug-automake@gnu.org about your system, including the value

8484         # when source code is being compiled.
8485         #
8486         # Problem is, this is at odds with the way Automake and most other
8487         # C build frameworks function, which is that the same flags used in
8488         # compilation (CFLAGS) are also used in linking.  Many systems

8491         # flag that is used only in the compilation phase and not in
8492         # linking.  Such a scenario is extremely rare in practice.
8493         #
8494         # Even though use of the -pthread flag in linking would only print
8495         # a warning, this can be a nuisance for well-run software projects
8496         # that build with -Werror.  So if the active version of Clang has
