1276 \`configure' configures this package to adapt to many kinds of systems.

1278 Usage: $0 [OPTION]... [VAR=VALUE]...
1279
1280 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1281 VAR=VALUE.  See below for descriptions of some of the useful variables.
1282
1283 Defaults for the options are specified in brackets.
1284
1285 Configuration:
1286   -h, --help              display this help and exit
1287       --help=short        display options specific to this package
1288       --help=recursive    display the short help of all the included packages
1289   -V, --version           display version information and exit
1290   -q, --quiet, --silent   do not print \`checking ...' messages
1291       --cache-file=FILE   cache test results in FILE [disabled]
1292   -C, --config-cache      alias for \`--cache-file=config.cache'
1293   -n, --no-create         do not create output files
1294       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1295
1296 Installation directories:
1297   --prefix=PREFIX         install architecture-independent files in PREFIX
1298                           [$ac_default_prefix]
1299   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1300                           [PREFIX]
1301
1302 By default, \`make install' will install all the files in
1303 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1304 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1305 for instance \`--prefix=\$HOME'.
1306
1307 For better control, use the options below.

1349                           enable make rules and dependencies not useful
1350                           (and sometimes confusing) to the casual installer
1351   --enable-multilib       build many library versions (default)

1355
1356 Optional Packages:
1357   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1358   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1359   --with-target-subdir=SUBDIR      Configuring in a subdirectory for target
1360   --with-build-subdir=SUBDIR       Configuring in a subdirectory for build
1361   --with-cross-host=HOST           Configuring with a cross compiler
1362   --with-newlib                    Configuring with newlib
1363
1364 Some influential environment variables:
1365   CC          C compiler command
1366   CFLAGS      C compiler flags
1367   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1368               nonstandard directory <lib dir>
1369   LIBS        libraries to pass to the linker, e.g. -l<library>
1370   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1371               you have headers in a nonstandard directory <include dir>
1372   CPP         C preprocessor
1373
1374 Use these variables to override the choices made by `configure' or to help
1375 it to find libraries and programs with nonstandard names/locations.

7449    Here is a matrix of mmap possibilities:
7450         mmap private not fixed
7451         mmap private fixed at somewhere currently unmapped
7452         mmap private fixed at somewhere already mapped
7453         mmap shared not fixed
7454         mmap shared fixed at somewhere currently unmapped
7455         mmap shared fixed at somewhere already mapped
7456    For private mappings, we should verify that changes cannot be read()
7457    back from the file, nor mmap's back from the file at a different
7458    address.  (There have been systems where private was not correctly
7459    implemented like the infamous i386 svr4.0, and systems where the
7460    VM page cache was not coherent with the file system buffer cache
7461    like early versions of FreeBSD and possibly contemporary NetBSD.)
7462    For shared mappings, we should conversely verify that changes get
7463    propagated back to all the places they're supposed to be.
7464
7465    Grep wants private fixed already mapped.
7466    The main things grep needs to know about mmap are:
7467    * does it exist and is it safe to write into the mmap'd area
7468    * how to use it (BSD variants)  */
