1270 \`configure' configures this package to adapt to many kinds of systems.

1272 Usage: $0 [OPTION]... [VAR=VALUE]...
1273
1274 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1275 VAR=VALUE.  See below for descriptions of some of the useful variables.
1276
1277 Defaults for the options are specified in brackets.
1278
1279 Configuration:
1280   -h, --help              display this help and exit
1281       --help=short        display options specific to this package
1282       --help=recursive    display the short help of all the included packages
1283   -V, --version           display version information and exit
1284   -q, --quiet, --silent   do not print \`checking ...' messages
1285       --cache-file=FILE   cache test results in FILE [disabled]
1286   -C, --config-cache      alias for \`--cache-file=config.cache'
1287   -n, --no-create         do not create output files
1288       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1289
1290 Installation directories:
1291   --prefix=PREFIX         install architecture-independent files in PREFIX
1292                           [$ac_default_prefix]
1293   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1294                           [PREFIX]
1295
1296 By default, \`make install' will install all the files in
1297 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1298 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1299 for instance \`--prefix=\$HOME'.
1300
1301 For better control, use the options below.

1349 Optional Packages:
1350   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1351   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1352   --with-target-subdir=SUBDIR      Configuring in a subdirectory for target
1353   --with-build-subdir=SUBDIR       Configuring in a subdirectory for build
1354   --with-cross-host=HOST           Configuring with a cross compiler
1355   --with-newlib                    Configuring with newlib
1356   --with-sphinx-build=    Use sphinx-build from a given path
1357
1358 Some influential environment variables:
1359   CC          C compiler command
1360   CFLAGS      C compiler flags
1361   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1362               nonstandard directory <lib dir>
1363   LIBS        libraries to pass to the linker, e.g. -l<library>
1364   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1365               you have headers in a nonstandard directory <include dir>
1366   CPP         C preprocessor
1367
1368 Use these variables to override the choices made by `configure' or to help
1369 it to find libraries and programs with nonstandard names/locations.

7515    Here is a matrix of mmap possibilities:
7516         mmap private not fixed
7517         mmap private fixed at somewhere currently unmapped
7518         mmap private fixed at somewhere already mapped
7519         mmap shared not fixed
7520         mmap shared fixed at somewhere currently unmapped
7521         mmap shared fixed at somewhere already mapped
7522    For private mappings, we should verify that changes cannot be read()
7523    back from the file, nor mmap's back from the file at a different
7524    address.  (There have been systems where private was not correctly
7525    implemented like the infamous i386 svr4.0, and systems where the
7526    VM page cache was not coherent with the file system buffer cache
7527    like early versions of FreeBSD and possibly contemporary NetBSD.)
7528    For shared mappings, we should conversely verify that changes get
7529    propagated back to all the places they're supposed to be.
7530
7531    Grep wants private fixed already mapped.
7532    The main things grep needs to know about mmap are:
7533    * does it exist and is it safe to write into the mmap'd area
7534    * how to use it (BSD variants)  */
