1266 \`configure' configures this package to adapt to many kinds of systems.
1268 Usage: $0 [OPTION]... [VAR=VALUE]...
1270 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1271 VAR=VALUE. See below for descriptions of some of the useful variables.
1273 Defaults for the options are specified in brackets.
1275 Configuration:
1276 -h, --help display this help and exit
1277 --help=short display options specific to this package
1278 --help=recursive display the short help of all the included packages
1279 -V, --version display version information and exit
1280 -q, --quiet, --silent do not print \`checking ...' messages
1281 --cache-file=FILE cache test results in FILE [disabled]
1282 -C, --config-cache alias for \`--cache-file=config.cache'
1283 -n, --no-create do not create output files
1284 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1286 Installation directories:
1287 --prefix=PREFIX install architecture-independent files in PREFIX
1288 [$ac_default_prefix]
1289 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1290 [PREFIX]
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'.
1297 For better control, use the options below.
1299 Fine tuning of the installation directories:
1300 --bindir=DIR user executables [EPREFIX/bin]
1301 --sbindir=DIR system admin executables [EPREFIX/sbin]
1302 --libexecdir=DIR program executables [EPREFIX/libexec]
1303 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1304 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
1305 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
1306 --libdir=DIR object code libraries [EPREFIX/lib]
1307 --includedir=DIR C header files [PREFIX/include]
1308 --oldincludedir=DIR C header files for non-gcc [/usr/include]
1309 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
1310 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
1311 --infodir=DIR info documentation [DATAROOTDIR/info]

1333 Optional Features:
1334 --disable-option-checking ignore unrecognized --enable/--with options
1335 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
1336 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1337 --enable-maintainer-mode
1338 enable make rules and dependencies not useful
1339 (and sometimes confusing) to the casual installer
1340 --enable-multilib build many library versions (default)
1341 --enable-install-libiberty Install headers and library for end users
1342 --disable-largefile omit support for large files
1343 --enable-cet enable Intel CET in host libraries [default=auto]
1345 Optional Packages:
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
1351 --with-newlib Configuring with newlib
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
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.
1366 Report bugs to the package provider.

7463 Here is a matrix of mmap possibilities:
7464 mmap private not fixed
7465 mmap private fixed at somewhere currently unmapped
7466 mmap private fixed at somewhere already mapped
7467 mmap shared not fixed
7468 mmap shared fixed at somewhere currently unmapped
7469 mmap shared fixed at somewhere already mapped
7470 For private mappings, we should verify that changes cannot be read()
7471 back from the file, nor mmap's back from the file at a different
7472 address. (There have been systems where private was not correctly
7473 implemented like the infamous i386 svr4.0, and systems where the
7474 VM page cache was not coherent with the file system buffer cache
7475 like early versions of FreeBSD and possibly contemporary NetBSD.)
7476 For shared mappings, we should conversely verify that changes get
7477 propagated back to all the places they're supposed to be.
7479 Grep wants private fixed already mapped.
7480 The main things grep needs to know about mmap are:
7481 * does it exist and is it safe to write into the mmap'd area
7482 * how to use it (BSD variants) */
