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.

1093   --disable-rpath         do not hardcode runtime library paths
1094
1095 Optional Packages:
1096   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1097   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1098   --with-x                use the X Window System

1108 Some influential environment variables:
1109   CC          C compiler command
1110   CFLAGS      C compiler flags
1111   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1112               nonstandard directory <lib dir>
1113   CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
1114               headers in a nonstandard directory <include dir>
1115   CXX         C++ compiler command
1116   CXXFLAGS    C++ compiler flags
1117   CPP         C preprocessor
1118
1119 Use these variables to override the choices made by `configure' or to help
1120 it to find libraries and programs with nonstandard names/locations.

10049 /* Thanks to Mike Haertel and Jim Avera for this test.
10050    Here is a matrix of mmap possibilities:
10051         mmap private not fixed
10052         mmap private fixed at somewhere currently unmapped
10053         mmap private fixed at somewhere already mapped
10054         mmap shared not fixed
10055         mmap shared fixed at somewhere currently unmapped
10056         mmap shared fixed at somewhere already mapped
10057    For private mappings, we should verify that changes cannot be read()
10058    back from the file, nor mmap's back from the file at a different
10059    address.  (There have been systems where private was not correctly
10060    implemented like the infamous i386 svr4.0, and systems where the
10061    VM page cache was not coherent with the file system buffer cache
10062    like early versions of FreeBSD and possibly contemporary NetBSD.)
10063    For shared mappings, we should conversely verify that changes get
10064    propagated back to all the places they're supposed to be.
10065
10066    Grep wants private fixed already mapped.
10067    The main things grep needs to know about mmap are:
10068    * does it exist and is it safe to write into the mmap'd area
10069    * how to use it (BSD variants)  */
