1232 \`configure' configures this package to adapt to many kinds of systems.
1233
1234 Usage: $0 [OPTION]... [VAR=VALUE]...
1235
1236 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1237 VAR=VALUE.  See below for descriptions of some of the useful variables.
1238
1239 Defaults for the options are specified in brackets.
1240
1241 Configuration:
1242   -h, --help              display this help and exit
1243       --help=short        display options specific to this package
1244       --help=recursive    display the short help of all the included packages
1245   -V, --version           display version information and exit
1246   -q, --quiet, --silent   do not print \`checking...' messages
1247       --cache-file=FILE   cache test results in FILE [disabled]
1248   -C, --config-cache      alias for \`--cache-file=config.cache'
1249   -n, --no-create         do not create output files
1250       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1251
1252 Installation directories:
1253   --prefix=PREFIX         install architecture-independent files in PREFIX
1254                           [$ac_default_prefix]
1255   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1256                           [PREFIX]
1257
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'.
1262
1263 For better control, use the options below.

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
1309
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
1317
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
1327
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.

7076    Here is a matrix of mmap possibilities:
7077         mmap private not fixed
7078         mmap private fixed at somewhere currently unmapped
7079         mmap private fixed at somewhere already mapped
7080         mmap shared not fixed
7081         mmap shared fixed at somewhere currently unmapped
7082         mmap shared fixed at somewhere already mapped
7083    For private mappings, we should verify that changes cannot be read()
7084    back from the file, nor mmap's back from the file at a different
7085    address.  (There have been systems where private was not correctly
7086    implemented like the infamous i386 svr4.0, and systems where the
7087    VM page cache was not coherent with the file system buffer cache
7088    like early versions of FreeBSD and possibly contemporary NetBSD.)
7089    For shared mappings, we should conversely verify that changes get
7090    propagated back to all the places they're supposed to be.
7091
7092    Grep wants private fixed already mapped.
7093    The main things grep needs to know about mmap are:
7094    * does it exist and is it safe to write into the mmap'd area
7095    * how to use it (BSD variants)  */
