1267 \`configure' configures this package to adapt to many kinds of systems.

1269 Usage: $0 [OPTION]... [VAR=VALUE]...
1270
1271 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1272 VAR=VALUE.  See below for descriptions of some of the useful variables.
1273
1274 Defaults for the options are specified in brackets.
1275
1276 Configuration:
1277   -h, --help              display this help and exit
1278       --help=short        display options specific to this package
1279       --help=recursive    display the short help of all the included packages
1280   -V, --version           display version information and exit
1281   -q, --quiet, --silent   do not print \`checking ...' messages
1282       --cache-file=FILE   cache test results in FILE [disabled]
1283   -C, --config-cache      alias for \`--cache-file=config.cache'
1284   -n, --no-create         do not create output files
1285       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1286
1287 Installation directories:
1288   --prefix=PREFIX         install architecture-independent files in PREFIX
1289                           [$ac_default_prefix]
1290   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1291                           [PREFIX]
1292
1293 By default, \`make install' will install all the files in
1294 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1295 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1296 for instance \`--prefix=\$HOME'.
1297
1298 For better control, use the options below.

1347   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1348   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1349   --with-target-subdir=SUBDIR      Configuring in a subdirectory for target
1350   --with-build-subdir=SUBDIR       Configuring in a subdirectory for build
1351   --with-cross-host=HOST           Configuring with a cross compiler

1354 Some influential environment variables:
1355   CC          C compiler command
1356   CFLAGS      C compiler flags
1357   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1358               nonstandard directory <lib dir>
1359   LIBS        libraries to pass to the linker, e.g. -l<library>
1360   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1361               you have headers in a nonstandard directory <include dir>
1362   CPP         C preprocessor
1363
1364 Use these variables to override the choices made by `configure' or to help
1365 it to find libraries and programs with nonstandard names/locations.

7432    Here is a matrix of mmap possibilities:
7433         mmap private not fixed
7434         mmap private fixed at somewhere currently unmapped
7435         mmap private fixed at somewhere already mapped
7436         mmap shared not fixed
7437         mmap shared fixed at somewhere currently unmapped
7438         mmap shared fixed at somewhere already mapped
7439    For private mappings, we should verify that changes cannot be read()
7440    back from the file, nor mmap's back from the file at a different
7441    address.  (There have been systems where private was not correctly
7442    implemented like the infamous i386 svr4.0, and systems where the
7443    VM page cache was not coherent with the file system buffer cache
7444    like early versions of FreeBSD and possibly contemporary NetBSD.)
7445    For shared mappings, we should conversely verify that changes get
7446    propagated back to all the places they're supposed to be.
7447
7448    Grep wants private fixed already mapped.
7449    The main things grep needs to know about mmap are:
7450    * does it exist and is it safe to write into the mmap'd area
7451    * how to use it (BSD variants)  */
