1319 \`configure' configures this package to adapt to many kinds of systems.
1320
1321 Usage: $0 [OPTION]... [VAR=VALUE]...
1322
1323 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1324 VAR=VALUE.  See below for descriptions of some of the useful variables.
1325
1326 Defaults for the options are specified in brackets.
1327
1328 Configuration:
1329   -h, --help              display this help and exit
1330       --help=short        display options specific to this package
1331       --help=recursive    display the short help of all the included packages
1332   -V, --version           display version information and exit
1333   -q, --quiet, --silent   do not print \`checking ...' messages
1334       --cache-file=FILE   cache test results in FILE [disabled]
1335   -C, --config-cache      alias for \`--cache-file=config.cache'
1336   -n, --no-create         do not create output files
1337       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1338
1339 Installation directories:
1340   --prefix=PREFIX         install architecture-independent files in PREFIX
1341                           [$ac_default_prefix]
1342   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1343                           [PREFIX]
1344
1345 By default, \`make install' will install all the files in
1346 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1347 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1348 for instance \`--prefix=\$HOME'.
1349
1350 For better control, use the options below.

1431 Some influential environment variables:
1432   CC          C compiler command
1433   CFLAGS      C compiler flags
1434   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1435               nonstandard directory <lib dir>
1436   LIBS        libraries to pass to the linker, e.g. -l<library>
1437   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1438               you have headers in a nonstandard directory <include dir>
1439   CXX         C++ compiler command
1440   CXXFLAGS    C++ compiler flags
1441   CPP         C preprocessor
1442
1443 Use these variables to override the choices made by `configure' or to help
1444 it to find libraries and programs with nonstandard names/locations.

6772         mmap shared fixed at somewhere already mapped
6773    For private mappings, we should verify that changes cannot be read()
6774    back from the file, nor mmap's back from the file at a different
6775    address.  (There have been systems where private was not correctly
6776    implemented like the infamous i386 svr4.0, and systems where the
6777    VM page cache was not coherent with the file system buffer cache
6778    like early versions of FreeBSD and possibly contemporary NetBSD.)
6779    For shared mappings, we should conversely verify that changes get
6780    propagated back to all the places they're supposed to be.
6781
6782    Grep wants private fixed already mapped.
6783    The main things grep needs to know about mmap are:
6784    * does it exist and is it safe to write into the mmap'd area
6785    * how to use it (BSD variants)  */
