944 nigel 53 \`configure' configures this package to adapt to many kinds of systems.
945    
946     Usage: $0 [OPTION]... [VAR=VALUE]...
947    
948     To assign environment variables (e.g., CC, CFLAGS...), specify them as
949     VAR=VALUE. See below for descriptions of some of the useful variables.
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
962     --srcdir=DIR find the sources in DIR [configure dir or \`..']

970     --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
971     [PREFIX]
972    
973     By default, \`make install' will install all the files in
974     \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
975     an installation prefix other than \`$ac_default_prefix' using \`--prefix',
976     for instance \`--prefix=\$HOME'.
977    
978     For better control, use the options below.

981     --bindir=DIR user executables [EPREFIX/bin]
982     --libdir=DIR object code libraries [EPREFIX/lib]
983     --includedir=DIR C header files [PREFIX/include]

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

1001     --enable-fast-install optimize for fast installation default=yes
1002     --disable-libtool-lock avoid locking (might break parallel builds)
1003 nigel 63 --enable-utf8 enable UTF8 support
1004     --enable-newline-is-cr use CR as the newline character
1005     --enable-newline-is-lf use LF as the newline character

1007     Optional Packages:

1010 nigel 63 --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 nigel 53
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.
