1231 \`configure' configures this package to adapt to many kinds of systems.
1232
1233 Usage: $0 [OPTION]... [VAR=VALUE]...
1234
1235 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1236 VAR=VALUE.  See below for descriptions of some of the useful variables.
1237
1238 Defaults for the options are specified in brackets.
1239
1240 Configuration:
1241   -h, --help              display this help and exit
1242       --help=short        display options specific to this package
1243       --help=recursive    display the short help of all the included packages
1244   -V, --version           display version information and exit
1245   -q, --quiet, --silent   do not print \`checking...' messages
1246       --cache-file=FILE   cache test results in FILE [disabled]
1247   -C, --config-cache      alias for \`--cache-file=config.cache'
1248   -n, --no-create         do not create output files
1249       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1250
1251 Installation directories:
1252   --prefix=PREFIX         install architecture-independent files in PREFIX
1253                           [$ac_default_prefix]
1254   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1255                           [PREFIX]
1256
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'.
1261
1262 For better control, use the options below.

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
1308
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
1316
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
1326
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.

6693    Here is a matrix of mmap possibilities:
6694         mmap private not fixed
6695         mmap private fixed at somewhere currently unmapped
6696         mmap private fixed at somewhere already mapped
6697         mmap shared not fixed
6698         mmap shared fixed at somewhere currently unmapped
6699         mmap shared fixed at somewhere already mapped
6700    For private mappings, we should verify that changes cannot be read()
6701    back from the file, nor mmap's back from the file at a different
6702    address.  (There have been systems where private was not correctly
6703    implemented like the infamous i386 svr4.0, and systems where the
6704    VM page cache was not coherent with the file system buffer cache
6705    like early versions of FreeBSD and possibly contemporary NetBSD.)
6706    For shared mappings, we should conversely verify that changes get
6707    propagated back to all the places they're supposed to be.
6708
6709    Grep wants private fixed already mapped.
6710    The main things grep needs to know about mmap are:
6711    * does it exist and is it safe to write into the mmap'd area
6712    * how to use it (BSD variants)  */
