1325 \`configure' configures this package to adapt to many kinds of systems.
1326
1327 Usage: $0 [OPTION]... [VAR=VALUE]...
1328
1329 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1330 VAR=VALUE.  See below for descriptions of some of the useful variables.
1331
1332 Defaults for the options are specified in brackets.
1333
1334 Configuration:
1335   -h, --help              display this help and exit
1336       --help=short        display options specific to this package
1337       --help=recursive    display the short help of all the included packages
1338   -V, --version           display version information and exit
1339   -q, --quiet, --silent   do not print \`checking ...' messages
1340       --cache-file=FILE   cache test results in FILE [disabled]
1341   -C, --config-cache      alias for \`--cache-file=config.cache'
1342   -n, --no-create         do not create output files
1343       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1344
1345 Installation directories:
1346   --prefix=PREFIX         install architecture-independent files in PREFIX
1347                           [$ac_default_prefix]
1348   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1349                           [PREFIX]
1350
1351 By default, \`make install' will install all the files in
1352 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1353 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1354 for instance \`--prefix=\$HOME'.
1355
1356 For better control, use the options below.

1441 Some influential environment variables:
1442   CC          C compiler command
1443   CFLAGS      C compiler flags
1444   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1445               nonstandard directory <lib dir>
1446   LIBS        libraries to pass to the linker, e.g. -l<library>
1447   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1448               you have headers in a nonstandard directory <include dir>
1449   CXX         C++ compiler command
1450   CXXFLAGS    C++ compiler flags
1451   CPP         C preprocessor
1452
1453 Use these variables to override the choices made by `configure' or to help
1454 it to find libraries and programs with nonstandard names/locations.

6776    Here is a matrix of mmap possibilities:
6777         mmap private not fixed
6778         mmap private fixed at somewhere currently unmapped
6779         mmap private fixed at somewhere already mapped
6780         mmap shared not fixed
6781         mmap shared fixed at somewhere currently unmapped
6782         mmap shared fixed at somewhere already mapped
6783    For private mappings, we should verify that changes cannot be read()
6784    back from the file, nor mmap's back from the file at a different
6785    address.  (There have been systems where private was not correctly
6786    implemented like the infamous i386 svr4.0, and systems where the
6787    VM page cache was not coherent with the file system buffer cache
6788    like early versions of FreeBSD and possibly contemporary NetBSD.)
6789    For shared mappings, we should conversely verify that changes get
6790    propagated back to all the places they're supposed to be.
6791
6792    Grep wants private fixed already mapped.
6793    The main things grep needs to know about mmap are:
6794    * does it exist and is it safe to write into the mmap'd area
6795    * how to use it (BSD variants)  */
