741     Usage: $0 [OPTION]... [VAR=VALUE]...
742    
743     To assign environment variables (e.g., CC, CFLAGS...), specify them as
744     VAR=VALUE. See below for descriptions of some of the useful variables.
745    
746     Defaults for the options are specified in brackets.
747    
748     Configuration:
749     -h, --help display this help and exit
750     --help=short display options specific to this package
751     --help=recursive display the short help of all the included packages
752     -V, --version display version information and exit
753     -q, --quiet, --silent do not print \`checking...' messages
754     --cache-file=FILE cache test results in FILE [disabled]
755     -C, --config-cache alias for \`--cache-file=config.cache'
756     -n, --no-create do not create output files
757     --srcdir=DIR find the sources in DIR [configure dir or \`..']

768     By default, \`make install' will install all the files in
769     \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
770     an installation prefix other than \`$ac_default_prefix' using \`--prefix',
