 792
 793 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 794 VAR=VALUE.  See below for descriptions of some of the useful variables.
 795
 796 Defaults for the options are specified in brackets.
 797
 798 Configuration:
 799   -h, --help              display this help and exit
 800       --help=short        display options specific to this package
 801       --help=recursive    display the short help of all the included packages
 802   -V, --version           display version information and exit
 803   -q, --quiet, --silent   do not print \`checking...' messages
 804       --cache-file=FILE   cache test results in FILE [disabled]
 805   -C, --config-cache      alias for \`--cache-file=config.cache'
 806   -n, --no-create         do not create output files
 807       --srcdir=DIR        find the sources in DIR [configure dir or \`..']

 820 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 821 for instance \`--prefix=\$HOME'.
