950    
951    Defaults for the options are specified in brackets.
952    
953    Configuration:
954      -h, --help              display this help and exit
955          --help=short        display options specific to this package
956          --help=recursive    display the short help of all the included packages
957      -V, --version           display version information and exit
958      -q, --quiet, --silent   do not print \`checking...' messages
959          --cache-file=FILE   cache test results in FILE [disabled]
960      -C, --config-cache      alias for \`--cache-file=config.cache'
961      -n, --no-create         do not create output files

1005      --enable-newline-is-lf  use LF as the newline character
1006    
1007    Optional Packages:

1009      --with-pic              try to use only PIC/non-PIC objects default=use both
1010      --with-posix-malloc-threshold=5  threshold for POSIX malloc usage
1011      --with-link-size=2    internal link size (2, 3, or 4 allowed)
1012      --with-match-limit=10000000      default limit on internal looping)
1013    
1014    Some influential environment variables:
1015      CC          C compiler command
1016      CFLAGS      C compiler flags
1017      LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1018                  nonstandard directory <lib dir>
1019      CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
1020                  headers in a nonstandard directory <include dir>
1021      CPP         C preprocessor
1022    
1023    Use these variables to override the choices made by `configure' or to help
1024    it to find libraries and programs with nonstandard names/locations.
