1266 \`configure' configures this package to adapt to many kinds of systems.

1268 Usage: $0 [OPTION]... [VAR=VALUE]...
1269
1270 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1271 VAR=VALUE.  See below for descriptions of some of the useful variables.
1272
1273 Defaults for the options are specified in brackets.
1274
1275 Configuration:
1276   -h, --help              display this help and exit
1277       --help=short        display options specific to this package
1278       --help=recursive    display the short help of all the included packages
1279   -V, --version           display version information and exit
1280   -q, --quiet, --silent   do not print \`checking ...' messages
1281       --cache-file=FILE   cache test results in FILE [disabled]
1282   -C, --config-cache      alias for \`--cache-file=config.cache'
1283   -n, --no-create         do not create output files
1284       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1285
1286 Installation directories:
1287   --prefix=PREFIX         install architecture-independent files in PREFIX
1288                           [$ac_default_prefix]
1289   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1290                           [PREFIX]
1291
1292 By default, \`make install' will install all the files in
1293 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1294 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1295 for instance \`--prefix=\$HOME'.
1296
1297 For better control, use the options below.

1346   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1347   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1348   --with-target-subdir=SUBDIR      Configuring in a subdirectory for target
1349   --with-build-subdir=SUBDIR       Configuring in a subdirectory for build
1350   --with-cross-host=HOST           Configuring with a cross compiler

1353 Some influential environment variables:
1354   CC          C compiler command
1355   CFLAGS      C compiler flags
1356   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1357               nonstandard directory <lib dir>
1358   LIBS        libraries to pass to the linker, e.g. -l<library>
1359   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1360               you have headers in a nonstandard directory <include dir>
1361   CPP         C preprocessor
1362
1363 Use these variables to override the choices made by `configure' or to help
1364 it to find libraries and programs with nonstandard names/locations.

7454    Here is a matrix of mmap possibilities:
7455         mmap private not fixed
7456         mmap private fixed at somewhere currently unmapped
7457         mmap private fixed at somewhere already mapped
7458         mmap shared not fixed
7459         mmap shared fixed at somewhere currently unmapped
7460         mmap shared fixed at somewhere already mapped
7461    For private mappings, we should verify that changes cannot be read()
7462    back from the file, nor mmap's back from the file at a different
7463    address.  (There have been systems where private was not correctly
7464    implemented like the infamous i386 svr4.0, and systems where the
7465    VM page cache was not coherent with the file system buffer cache
7466    like early versions of FreeBSD and possibly contemporary NetBSD.)
7467    For shared mappings, we should conversely verify that changes get
7468    propagated back to all the places they're supposed to be.
7469
7470    Grep wants private fixed already mapped.
7471    The main things grep needs to know about mmap are:
7472    * does it exist and is it safe to write into the mmap'd area
7473    * how to use it (BSD variants)  */
