1592 Usage: $0 [OPTION]... [VAR=VALUE]...
1593
1594 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1595 VAR=VALUE.  See below for descriptions of some of the useful variables.
1596
1597 Defaults for the options are specified in brackets.
1598
1599 Configuration:
1600   -h, --help              display this help and exit
1601       --help=short        display options specific to this package
1602       --help=recursive    display the short help of all the included packages
1603   -V, --version           display version information and exit
1604   -q, --quiet, --silent   do not print \`checking ...' messages
1605       --cache-file=FILE   cache test results in FILE [disabled]
1606   -C, --config-cache      alias for \`--cache-file=config.cache'
1607   -n, --no-create         do not create output files
1608       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1609
1610 Installation directories:
1611   --prefix=PREFIX         install architecture-independent files in PREFIX
1612                           [$ac_default_prefix]
1613   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1614                           [PREFIX]
1615
1616 By default, \`make install' will install all the files in
1617 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1618 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1619 for instance \`--prefix=\$HOME'.

1875   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1876               nonstandard directory <lib dir>
1877   LIBS        libraries to pass to the linker, e.g. -l<library>
1878   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1879               you have headers in a nonstandard directory <include dir>
1880   CXX         C++ compiler command
1881   CXXFLAGS    C++ compiler flags
1882   CXXCPP      C++ preprocessor
1883   CPP         C preprocessor
1884   GMPLIBS     How to link GMP
1885   GMPINC      How to find GMP include files
