1263 \`configure' configures this package to adapt to many kinds of systems.
1264
1265 Usage: $0 [OPTION]... [VAR=VALUE]...
1266
1267 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1268 VAR=VALUE.  See below for descriptions of some of the useful variables.
1269
1270 Defaults for the options are specified in brackets.
1271
1272 Configuration:
1273   -h, --help              display this help and exit
1274       --help=short        display options specific to this package
1275       --help=recursive    display the short help of all the included packages
1276   -V, --version           display version information and exit
1277   -q, --quiet, --silent   do not print \`checking ...' messages
1278       --cache-file=FILE   cache test results in FILE [disabled]
1279   -C, --config-cache      alias for \`--cache-file=config.cache'
1280   -n, --no-create         do not create output files
1281       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1282
1283 Installation directories:
1284   --prefix=PREFIX         install architecture-independent files in PREFIX
1285                           [$ac_default_prefix]
1286   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1287                           [PREFIX]
1288
1289 By default, \`make install' will install all the files in
1290 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1291 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1292 for instance \`--prefix=\$HOME'.
1293
1294 For better control, use the options below.

1349 Some influential environment variables:
1350   CC          C compiler command
1351   CFLAGS      C compiler flags
1352   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1353               nonstandard directory <lib dir>
1354   LIBS        libraries to pass to the linker, e.g. -l<library>
1355   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1356               you have headers in a nonstandard directory <include dir>
1357   CPP         C preprocessor
1358
1359 Use these variables to override the choices made by `configure' or to help
1360 it to find libraries and programs with nonstandard names/locations.

7202    Here is a matrix of mmap possibilities:
7203         mmap private not fixed
7204         mmap private fixed at somewhere currently unmapped
7205         mmap private fixed at somewhere already mapped
7206         mmap shared not fixed
7207         mmap shared fixed at somewhere currently unmapped
7208         mmap shared fixed at somewhere already mapped
7209    For private mappings, we should verify that changes cannot be read()
7210    back from the file, nor mmap's back from the file at a different
7211    address.  (There have been systems where private was not correctly
7212    implemented like the infamous i386 svr4.0, and systems where the
7213    VM page cache was not coherent with the file system buffer cache
7214    like early versions of FreeBSD and possibly contemporary NetBSD.)
7215    For shared mappings, we should conversely verify that changes get
7216    propagated back to all the places they're supposed to be.
7217
7218    Grep wants private fixed already mapped.
7219    The main things grep needs to know about mmap are:
7220    * does it exist and is it safe to write into the mmap'd area
7221    * how to use it (BSD variants)  */
