1231 \`configure' configures this package to adapt to many kinds of systems.
1233 Usage: $0 [OPTION]... [VAR=VALUE]...
1235 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1236 VAR=VALUE. See below for descriptions of some of the useful variables.
1238 Defaults for the options are specified in brackets.
1240 Configuration:
1241 -h, --help display this help and exit
1242 --help=short display options specific to this package
1243 --help=recursive display the short help of all the included packages
1244 -V, --version display version information and exit
1245 -q, --quiet, --silent do not print \`checking...' messages
1246 --cache-file=FILE cache test results in FILE [disabled]
1247 -C, --config-cache alias for \`--cache-file=config.cache'
1248 -n, --no-create do not create output files
1249 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1251 Installation directories:
1252 --prefix=PREFIX install architecture-independent files in PREFIX
1253 [$ac_default_prefix]
1254 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1255 [PREFIX]
1257 By default, \`make install' will install all the files in
1258 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1259 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1260 for instance \`--prefix=\$HOME'.
1262 For better control, use the options below.
1264 Fine tuning of the installation directories:
1265 --bindir=DIR user executables [EPREFIX/bin]
1266 --sbindir=DIR system admin executables [EPREFIX/sbin]
1267 --libexecdir=DIR program executables [EPREFIX/libexec]
1268 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1269 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
1270 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
1271 --libdir=DIR object code libraries [EPREFIX/lib]
1272 --includedir=DIR C header files [PREFIX/include]
1273 --oldincludedir=DIR C header files for non-gcc [/usr/include]
1274 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
1275 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
1276 --infodir=DIR info documentation [DATAROOTDIR/info]

1298 Optional Features:
1299 --disable-option-checking ignore unrecognized --enable/--with options
1300 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
1301 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1302 --enable-maintainer-mode
1303 enable make rules and dependencies not useful
1304 (and sometimes confusing) to the casual installer
1305 --enable-multilib build many library versions (default)
1306 --enable-install-libiberty Install headers and library for end users
1307 --disable-largefile omit support for large files
1309 Optional Packages:
1310 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1311 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1312 --with-target-subdir=SUBDIR Configuring in a subdirectory for target
1313 --with-build-subdir=SUBDIR Configuring in a subdirectory for build
1314 --with-cross-host=HOST Configuring with a cross compiler
1315 --with-newlib Configuring with newlib
1317 Some influential environment variables:
1318 CC C compiler command
1319 CFLAGS C compiler flags
1320 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1321 nonstandard directory <lib dir>
1322 LIBS libraries to pass to the linker, e.g. -l<library>
1323 CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1324 you have headers in a nonstandard directory <include dir>
1325 CPP C preprocessor
1327 Use these variables to override the choices made by `configure' or to help
1328 it to find libraries and programs with nonstandard names/locations.
1330 Report bugs to the package provider.

6696 Here is a matrix of mmap possibilities:
6697 mmap private not fixed
6698 mmap private fixed at somewhere currently unmapped
6699 mmap private fixed at somewhere already mapped
6700 mmap shared not fixed
6701 mmap shared fixed at somewhere currently unmapped
6702 mmap shared fixed at somewhere already mapped
6703 For private mappings, we should verify that changes cannot be read()
6704 back from the file, nor mmap's back from the file at a different
6705 address. (There have been systems where private was not correctly
6706 implemented like the infamous i386 svr4.0, and systems where the
6707 VM page cache was not coherent with the file system buffer cache
6708 like early versions of FreeBSD and possibly contemporary NetBSD.)
6709 For shared mappings, we should conversely verify that changes get
6710 propagated back to all the places they're supposed to be.
6712 Grep wants private fixed already mapped.
6713 The main things grep needs to know about mmap are:
6714 * does it exist and is it safe to write into the mmap'd area
6715 * how to use it (BSD variants) */
