 955 \`configure' configures this package to adapt to many kinds of systems.

 957 Usage: $0 [OPTION]... [VAR=VALUE]...
 958
 959 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 960 VAR=VALUE.  See below for descriptions of some of the useful variables.
 961
 962 Defaults for the options are specified in brackets.
 963
 964 Configuration:
 965   -h, --help              display this help and exit
 966       --help=short        display options specific to this package
 967       --help=recursive    display the short help of all the included packages
 968   -V, --version           display version information and exit
 969   -q, --quiet, --silent   do not print \`checking...' messages
 970       --cache-file=FILE   cache test results in FILE [disabled]
 971   -C, --config-cache      alias for \`--cache-file=config.cache'
 972   -n, --no-create         do not create output files
 973       --srcdir=DIR        find the sources in DIR [configure dir or \`..']

 981   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
 982                           [PREFIX]
 983
 984 By default, \`make install' will install all the files in
 985 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 986 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 987 for instance \`--prefix=\$HOME'.

 989 For better control, use the options below.

1047   CC          C compiler command
1048   CFLAGS      C compiler flags
1049   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1050               nonstandard directory <lib dir>
1051   CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
