1232 \`configure' configures this package to adapt to many kinds of systems.
1234 Usage: $0 [OPTION]... [VAR=VALUE]...
1236 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1237 VAR=VALUE. See below for descriptions of some of the useful variables.
1239 Defaults for the options are specified in brackets.
1241 Configuration:
1242 -h, --help display this help and exit
1243 --help=short display options specific to this package
1244 --help=recursive display the short help of all the included packages
1245 -V, --version display version information and exit
1246 -q, --quiet, --silent do not print \`checking...' messages
1247 --cache-file=FILE cache test results in FILE [disabled]
1248 -C, --config-cache alias for \`--cache-file=config.cache'
1249 -n, --no-create do not create output files
1250 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1252 Installation directories:
1253 --prefix=PREFIX install architecture-independent files in PREFIX
1254 [$ac_default_prefix]
1255 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1256 [PREFIX]
1258 By default, \`make install' will install all the files in
1259 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1260 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1261 for instance \`--prefix=\$HOME'.
1263 For better control, use the options below.
1265 Fine tuning of the installation directories:
1266 --bindir=DIR user executables [EPREFIX/bin]
1267 --sbindir=DIR system admin executables [EPREFIX/sbin]
1268 --libexecdir=DIR program executables [EPREFIX/libexec]
1269 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1270 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
1271 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
1272 --libdir=DIR object code libraries [EPREFIX/lib]
1273 --includedir=DIR C header files [PREFIX/include]
1274 --oldincludedir=DIR C header files for non-gcc [/usr/include]
1275 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
1276 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
1277 --infodir=DIR info documentation [DATAROOTDIR/info]

1299 Optional Features:
1300 --disable-option-checking ignore unrecognized --enable/--with options
1301 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
1302 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1303 --enable-maintainer-mode
1304 enable make rules and dependencies not useful
1305 (and sometimes confusing) to the casual installer
1306 --enable-multilib build many library versions (default)
1307 --enable-install-libiberty Install headers and library for end users
1308 --disable-largefile omit support for large files
1310 Optional Packages:
1311 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1312 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1313 --with-target-subdir=SUBDIR Configuring in a subdirectory for target
1314 --with-build-subdir=SUBDIR Configuring in a subdirectory for build
1315 --with-cross-host=HOST Configuring with a cross compiler
1316 --with-newlib Configuring with newlib
1318 Some influential environment variables:
1319 CC C compiler command
1320 CFLAGS C compiler flags
1321 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1322 nonstandard directory <lib dir>
1323 LIBS libraries to pass to the linker, e.g. -l<library>
1324 CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1325 you have headers in a nonstandard directory <include dir>
1326 CPP C preprocessor
1328 Use these variables to override the choices made by `configure' or to help
1329 it to find libraries and programs with nonstandard names/locations.
1331 Report bugs to the package provider.

6699 Here is a matrix of mmap possibilities:
6700 mmap private not fixed
6701 mmap private fixed at somewhere currently unmapped
6702 mmap private fixed at somewhere already mapped
6703 mmap shared not fixed
6704 mmap shared fixed at somewhere currently unmapped
6705 mmap shared fixed at somewhere already mapped
6706 For private mappings, we should verify that changes cannot be read()
6707 back from the file, nor mmap's back from the file at a different
6708 address. (There have been systems where private was not correctly
6709 implemented like the infamous i386 svr4.0, and systems where the
6710 VM page cache was not coherent with the file system buffer cache
6711 like early versions of FreeBSD and possibly contemporary NetBSD.)
6712 For shared mappings, we should conversely verify that changes get
6713 propagated back to all the places they're supposed to be.
6715 Grep wants private fixed already mapped.
6716 The main things grep needs to know about mmap are:
6717 * does it exist and is it safe to write into the mmap'd area
6718 * how to use it (BSD variants) */
