1265 \`configure' configures this package to adapt to many kinds of systems.
1267 Usage: $0 [OPTION]... [VAR=VALUE]...
1269 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1270 VAR=VALUE. See below for descriptions of some of the useful variables.
1272 Defaults for the options are specified in brackets.
1274 Configuration:
1275 -h, --help display this help and exit
1276 --help=short display options specific to this package
1277 --help=recursive display the short help of all the included packages
1278 -V, --version display version information and exit
1279 -q, --quiet, --silent do not print \`checking ...' messages
1280 --cache-file=FILE cache test results in FILE [disabled]
1281 -C, --config-cache alias for \`--cache-file=config.cache'
1282 -n, --no-create do not create output files
1283 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1285 Installation directories:
1286 --prefix=PREFIX install architecture-independent files in PREFIX
1287 [$ac_default_prefix]
1288 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1289 [PREFIX]
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'.
1296 For better control, use the options below.
1298 Fine tuning of the installation directories:
1299 --bindir=DIR user executables [EPREFIX/bin]
1300 --sbindir=DIR system admin executables [EPREFIX/sbin]
1301 --libexecdir=DIR program executables [EPREFIX/libexec]
1302 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1303 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
1304 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
1305 --libdir=DIR object code libraries [EPREFIX/lib]
1306 --includedir=DIR C header files [PREFIX/include]
1307 --oldincludedir=DIR C header files for non-gcc [/usr/include]
1308 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
1309 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
1310 --infodir=DIR info documentation [DATAROOTDIR/info]

1332 Optional Features:
1333 --disable-option-checking ignore unrecognized --enable/--with options
1334 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
1335 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1336 --enable-maintainer-mode
1337 enable make rules and dependencies not useful
1338 (and sometimes confusing) to the casual installer
1339 --enable-multilib build many library versions (default)
1340 --enable-install-libiberty Install headers and library for end users
1341 --disable-largefile omit support for large files
1342 --enable-cet enable Intel CET in host libraries [default=auto]
1344 Optional Packages:
1345 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
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
1350 --with-newlib Configuring with newlib
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
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.
1365 Report bugs to the package provider.

7448 Here is a matrix of mmap possibilities:
7449 mmap private not fixed
7450 mmap private fixed at somewhere currently unmapped
7451 mmap private fixed at somewhere already mapped
7452 mmap shared not fixed
7453 mmap shared fixed at somewhere currently unmapped
7454 mmap shared fixed at somewhere already mapped
7455 For private mappings, we should verify that changes cannot be read()
7456 back from the file, nor mmap's back from the file at a different
7457 address. (There have been systems where private was not correctly
7458 implemented like the infamous i386 svr4.0, and systems where the
7459 VM page cache was not coherent with the file system buffer cache
7460 like early versions of FreeBSD and possibly contemporary NetBSD.)
7461 For shared mappings, we should conversely verify that changes get
7462 propagated back to all the places they're supposed to be.
7464 Grep wants private fixed already mapped.
7465 The main things grep needs to know about mmap are:
7466 * does it exist and is it safe to write into the mmap'd area
7467 * how to use it (BSD variants) */
