947 nigel 53 \`configure' configures this package to adapt to many kinds of systems.
948    
949     Usage: $0 [OPTION]... [VAR=VALUE]...
950    
951     To assign environment variables (e.g., CC, CFLAGS...), specify them as
952     VAR=VALUE. See below for descriptions of some of the useful variables.
953    
954     Defaults for the options are specified in brackets.
955    
956     Configuration:
957     -h, --help display this help and exit
958     --help=short display options specific to this package
959     --help=recursive display the short help of all the included packages
960     -V, --version display version information and exit
961     -q, --quiet, --silent do not print \`checking...' messages
962     --cache-file=FILE cache test results in FILE [disabled]
963     -C, --config-cache alias for \`--cache-file=config.cache'
964     -n, --no-create do not create output files
965     --srcdir=DIR find the sources in DIR [configure dir or \`..']

973     --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX

975    
976     By default, \`make install' will install all the files in
977     \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
978     an installation prefix other than \`$ac_default_prefix' using \`--prefix',
979     for instance \`--prefix=\$HOME'.
980

999     Optional Features:

1002     --enable-shared build shared libraries default=yes

1004     --enable-fast-install optimize for fast installation default=yes
1005     --disable-libtool-lock avoid locking (might break parallel builds)
1006 nigel 63 --enable-utf8 enable UTF8 support
1007     --enable-newline-is-cr use CR as the newline character

1009 nigel 73 --enable-ebcdic assume EBCDIC coding rather than ASCII
1010     --disable-stack-for-recursion disable use of stack recursion when matching

1012     Optional Packages:

1015 nigel 63 --with-posix-malloc-threshold=5 threshold for POSIX malloc usage
1016     --with-link-size=2 internal link size (2, 3, or 4 allowed)
1017     --with-match-limit=10000000 default limit on internal looping)

1019     Some influential environment variables:
1020     CC C compiler command
1021     CFLAGS C compiler flags
1022     LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1023     nonstandard directory <lib dir>
1024     CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have
1025     headers in a nonstandard directory <include dir>
1026     CPP C preprocessor
1027    
1028     Use these variables to override the choices made by `configure' or to help
1029     it to find libraries and programs with nonstandard names/locations.
