1582 Usage: $0 [OPTION]... [VAR=VALUE]...
1583
1584 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1585 VAR=VALUE.  See below for descriptions of some of the useful variables.
1586
1587 Defaults for the options are specified in brackets.
1588
1589 Configuration:
1590   -h, --help              display this help and exit
1591       --help=short        display options specific to this package
1592       --help=recursive    display the short help of all the included packages
1593   -V, --version           display version information and exit
1594   -q, --quiet, --silent   do not print \`checking ...' messages
1595       --cache-file=FILE   cache test results in FILE [disabled]
1596   -C, --config-cache      alias for \`--cache-file=config.cache'
1597   -n, --no-create         do not create output files
1598       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1599
1600 Installation directories:
1601   --prefix=PREFIX         install architecture-independent files in PREFIX
1602                           [$ac_default_prefix]
1603   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1604                           [PREFIX]
1605
1606 By default, \`make install' will install all the files in
1607 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1608 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1609 for instance \`--prefix=\$HOME'.

1853   CFLAGS      C compiler flags
1854   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1855               nonstandard directory <lib dir>
1856   LIBS        libraries to pass to the linker, e.g. -l<library>
1857   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1858               you have headers in a nonstandard directory <include dir>
1859   CXX         C++ compiler command
1860   CXXFLAGS    C++ compiler flags
1861   CXXCPP      C++ preprocessor
1862   CPP         C preprocessor
1863   GMPLIBS     How to link GMP
