1023 \`configure' configures this package to adapt to many kinds of systems.
1024
1025 Usage: $0 [OPTION]... [VAR=VALUE]...
1026
1027 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1028 VAR=VALUE.  See below for descriptions of some of the useful variables.
1029
1030 Defaults for the options are specified in brackets.
1031
1032 Configuration:
1033   -h, --help              display this help and exit
1034       --help=short        display options specific to this package
1035       --help=recursive    display the short help of all the included packages
1036   -V, --version           display version information and exit
1037   -q, --quiet, --silent   do not print \`checking...' messages
1038       --cache-file=FILE   cache test results in FILE [disabled]
1039   -C, --config-cache      alias for \`--cache-file=config.cache'
1040   -n, --no-create         do not create output files
1041       --srcdir=DIR        find the sources in DIR [configure dir or \`..']

1046 Installation directories:
1047   --prefix=PREFIX         install architecture-independent files in PREFIX
1048                           [$ac_default_prefix]
1049   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1050                           [PREFIX]
1051
1052 By default, \`make install' will install all the files in
1053 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1054 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1055 for instance \`--prefix=\$HOME'.
1056
1057 For better control, use the options below.
1058
1059 Fine tuning of the installation directories:
1060   --bindir=DIR           user executables [EPREFIX/bin]
1061   --sbindir=DIR          system admin executables [EPREFIX/sbin]
1062   --libexecdir=DIR       program executables [EPREFIX/libexec]
1063   --datadir=DIR          read-only architecture-independent data [PREFIX/share]
1064   --sysconfdir=DIR       read-only single-machine data [PREFIX/etc]
1065   --sharedstatedir=DIR   modifiable architecture-independent data [PREFIX/com]
1066   --localstatedir=DIR    modifiable single-machine data [PREFIX/var]
1067   --libdir=DIR           object code libraries [EPREFIX/lib]
1068   --includedir=DIR       C header files [PREFIX/include]
1069   --oldincludedir=DIR    C header files for non-gcc [/usr/include]
1070   --infodir=DIR          info documentation [PREFIX/info]
1071   --mandir=DIR           man documentation [PREFIX/man]

1087   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1088   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1089   --with-x                use the X Window System
1090        --with-appresdir=DIR    X11 application resource files

1092 Some influential environment variables:
1093   CC          C compiler command
1094   CFLAGS      C compiler flags
1095   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1096               nonstandard directory <lib dir>
1097   CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
1098               headers in a nonstandard directory <include dir>
1099   CXX         C++ compiler command
1100   CXXFLAGS    C++ compiler flags
1101   CPP         C preprocessor
1102
1103 Use these variables to override the choices made by `configure' or to help
1104 it to find libraries and programs with nonstandard names/locations.

8824    Here is a matrix of mmap possibilities:
8825         mmap private not fixed
8826         mmap private fixed at somewhere currently unmapped
8827         mmap private fixed at somewhere already mapped
8828         mmap shared not fixed
8829         mmap shared fixed at somewhere currently unmapped
8830         mmap shared fixed at somewhere already mapped
8831    For private mappings, we should verify that changes cannot be read()
8832    back from the file, nor mmap's back from the file at a different
8833    address.  (There have been systems where private was not correctly
8834    implemented like the infamous i386 svr4.0, and systems where the
8835    VM page cache was not coherent with the file system buffer cache
8836    like early versions of FreeBSD and possibly contemporary NetBSD.)
8837    For shared mappings, we should conversely verify that changes get
8838    propagated back to all the places they're supposed to be.
8839
8840    Grep wants private fixed already mapped.
8841    The main things grep needs to know about mmap are:
8842    * does it exist and is it safe to write into the mmap'd area
8843    * how to use it (BSD variants)  */
