1011 \`configure' configures this package to adapt to many kinds of systems.
1012
1013 Usage: $0 [OPTION]... [VAR=VALUE]...
1014
1015 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1016 VAR=VALUE.  See below for descriptions of some of the useful variables.
1017
1018 Defaults for the options are specified in brackets.
1019
1020 Configuration:
1021   -h, --help              display this help and exit
1022       --help=short        display options specific to this package
1023       --help=recursive    display the short help of all the included packages
1024   -V, --version           display version information and exit
1025   -q, --quiet, --silent   do not print \`checking...' messages
1026       --cache-file=FILE   cache test results in FILE [disabled]
1027   -C, --config-cache      alias for \`--cache-file=config.cache'
1028   -n, --no-create         do not create output files
1029       --srcdir=DIR        find the sources in DIR [configure dir or \`..']

1034 Installation directories:
1035   --prefix=PREFIX         install architecture-independent files in PREFIX
1036                           [$ac_default_prefix]
1037   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1038                           [PREFIX]
1039
1040 By default, \`make install' will install all the files in
1041 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1042 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1043 for instance \`--prefix=\$HOME'.
1044
1045 For better control, use the options below.
1046
1047 Fine tuning of the installation directories:
1048   --bindir=DIR           user executables [EPREFIX/bin]
1049   --sbindir=DIR          system admin executables [EPREFIX/sbin]
1050   --libexecdir=DIR       program executables [EPREFIX/libexec]

1054   --localstatedir=DIR    modifiable single-machine data [PREFIX/var]
1055   --libdir=DIR           object code libraries [EPREFIX/lib]
1056   --includedir=DIR       C header files [PREFIX/include]
1057   --oldincludedir=DIR    C header files for non-gcc [/usr/include]
1058   --infodir=DIR          info documentation [PREFIX/info]

1075   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1076   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1077   --with-x                use the X Window System
1078        --with-appresdir=DIR    X11 application resource files

1080 Some influential environment variables:
1081   CC          C compiler command
1082   CFLAGS      C compiler flags
1083   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1084               nonstandard directory <lib dir>
1085   CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
1086               headers in a nonstandard directory <include dir>
1087   CXX         C++ compiler command
1088   CXXFLAGS    C++ compiler flags
1089   CPP         C preprocessor
1090
1091 Use these variables to override the choices made by `configure' or to help
1092 it to find libraries and programs with nonstandard names/locations.

8615    For private mappings, we should verify that changes cannot be read()
8616    back from the file, nor mmap's back from the file at a different
8617    address.  (There have been systems where private was not correctly
8618    implemented like the infamous i386 svr4.0, and systems where the
8619    VM page cache was not coherent with the file system buffer cache
8620    like early versions of FreeBSD and possibly contemporary NetBSD.)
8621    For shared mappings, we should conversely verify that changes get
8622    propagated back to all the places they're supposed to be.
8623
8624    Grep wants private fixed already mapped.
8625    The main things grep needs to know about mmap are:
8626    * does it exist and is it safe to write into the mmap'd area
8627    * how to use it (BSD variants)  */
