1265 \`configure' configures this package to adapt to many kinds of systems.

1267 Usage: $0 [OPTION]... [VAR=VALUE]...
1268
1269 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1270 VAR=VALUE.  See below for descriptions of some of the useful variables.
1271
1272 Defaults for the options are specified in brackets.
1273
1274 Configuration:
1275   -h, --help              display this help and exit
1276       --help=short        display options specific to this package
1277       --help=recursive    display the short help of all the included packages
1278   -V, --version           display version information and exit
1279   -q, --quiet, --silent   do not print \`checking ...' messages
1280       --cache-file=FILE   cache test results in FILE [disabled]
1281   -C, --config-cache      alias for \`--cache-file=config.cache'
1282   -n, --no-create         do not create output files
1283       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1284
1285 Installation directories:
1286   --prefix=PREFIX         install architecture-independent files in PREFIX
1287                           [$ac_default_prefix]
1288   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1289                           [PREFIX]
1290
1291 By default, \`make install' will install all the files in
1292 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1293 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1294 for instance \`--prefix=\$HOME'.
1295
1296 For better control, use the options below.

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

1352 Some influential environment variables:
1353   CC          C compiler command
1354   CFLAGS      C compiler flags
1355   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1356               nonstandard directory <lib dir>
1357   LIBS        libraries to pass to the linker, e.g. -l<library>
1358   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1359               you have headers in a nonstandard directory <include dir>
1360   CPP         C preprocessor
1361
1362 Use these variables to override the choices made by `configure' or to help
1363 it to find libraries and programs with nonstandard names/locations.

7395    Here is a matrix of mmap possibilities:
7396         mmap private not fixed
7397         mmap private fixed at somewhere currently unmapped
7398         mmap private fixed at somewhere already mapped
7399         mmap shared not fixed
7400         mmap shared fixed at somewhere currently unmapped
7401         mmap shared fixed at somewhere already mapped
7402    For private mappings, we should verify that changes cannot be read()
7403    back from the file, nor mmap's back from the file at a different
7404    address.  (There have been systems where private was not correctly
7405    implemented like the infamous i386 svr4.0, and systems where the
7406    VM page cache was not coherent with the file system buffer cache
7407    like early versions of FreeBSD and possibly contemporary NetBSD.)
7408    For shared mappings, we should conversely verify that changes get
7409    propagated back to all the places they're supposed to be.
7410
7411    Grep wants private fixed already mapped.
7412    The main things grep needs to know about mmap are:
7413    * does it exist and is it safe to write into the mmap'd area
7414    * how to use it (BSD variants)  */
