1268 \`configure' configures this package to adapt to many kinds of systems.

1270 Usage: $0 [OPTION]... [VAR=VALUE]...
1271
1272 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1273 VAR=VALUE. See below for descriptions of some of the useful variables.
1274
1275 Defaults for the options are specified in brackets.
1276
1277 Configuration:
1278 -h, --help display this help and exit
1279 --help=short display options specific to this package
1280 --help=recursive display the short help of all the included packages
1281 -V, --version display version information and exit
1282 -q, --quiet, --silent do not print \`checking ...' messages
1283 --cache-file=FILE cache test results in FILE [disabled]
1284 -C, --config-cache alias for \`--cache-file=config.cache'
1285 -n, --no-create do not create output files
1286 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1287
1288 Installation directories:
1289 --prefix=PREFIX install architecture-independent files in PREFIX
1290 [$ac_default_prefix]
1291 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1292 [PREFIX]
1293
1294 By default, \`make install' will install all the files in
1295 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1296 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1297 for instance \`--prefix=\$HOME'.
1298
1299 For better control, use the options below.
1300
1301 Fine tuning of the installation directories:
1302 --bindir=DIR user executables [EPREFIX/bin]
1303 --sbindir=DIR system admin executables [EPREFIX/sbin]
1304 --libexecdir=DIR program executables [EPREFIX/libexec]
1305 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1306 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
1307 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
1308 --libdir=DIR object code libraries [EPREFIX/lib]
1309 --includedir=DIR C header files [PREFIX/include]
1310 --oldincludedir=DIR C header files for non-gcc [/usr/include]
1311 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]

1337 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
1338 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1339 --enable-maintainer-mode
1340 enable make rules and dependencies not useful
1341 (and sometimes confusing) to the casual installer
1342 --enable-multilib build many library versions (default)
1343 --enable-install-libiberty Install headers and library for end users
1344 --disable-largefile omit support for large files
1345 --enable-cet enable Intel CET in host libraries [default=auto]
1346
1347 Optional Packages:
1348 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1349 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1350 --with-target-subdir=SUBDIR Configuring in a subdirectory for target
1351 --with-build-subdir=SUBDIR Configuring in a subdirectory for build
1352 --with-cross-host=HOST Configuring with a cross compiler
1353 --with-newlib Configuring with newlib
1354
1355 Some influential environment variables:
1356 CC C compiler command
1357 CFLAGS C compiler flags
1358 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1359 nonstandard directory <lib dir>
1360 LIBS libraries to pass to the linker, e.g. -l<library>
1361 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1362 you have headers in a nonstandard directory <include dir>
1363 CPP C preprocessor
1364
1365 Use these variables to override the choices made by `configure' or to help
1366 it to find libraries and programs with nonstandard names/locations.
1367

7592 Here is a matrix of mmap possibilities:
7593 mmap private not fixed
7594 mmap private fixed at somewhere currently unmapped
7595 mmap private fixed at somewhere already mapped
7596 mmap shared not fixed
7597 mmap shared fixed at somewhere currently unmapped
7598 mmap shared fixed at somewhere already mapped
7599 For private mappings, we should verify that changes cannot be read()
7600 back from the file, nor mmap's back from the file at a different
7601 address. (There have been systems where private was not correctly
7602 implemented like the infamous i386 svr4.0, and systems where the
7603 VM page cache was not coherent with the file system buffer cache
7604 like early versions of FreeBSD and possibly contemporary NetBSD.)
7605 For shared mappings, we should conversely verify that changes get
7606 propagated back to all the places they're supposed to be.
7607
7608 Grep wants private fixed already mapped.
7609 The main things grep needs to know about mmap are:
7610 * does it exist and is it safe to write into the mmap'd area
7611 * how to use it (BSD variants) */
