1245 \`configure' configures this package to adapt to many kinds of systems.
1246
1247 Usage: $0 [OPTION]... [VAR=VALUE]...
1248
1249 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1250 VAR=VALUE.  See below for descriptions of some of the useful variables.
1251
1252 Defaults for the options are specified in brackets.
1253
1254 Configuration:
1255   -h, --help              display this help and exit
1256       --help=short        display options specific to this package
1257       --help=recursive    display the short help of all the included packages
1258   -V, --version           display version information and exit
1259   -q, --quiet, --silent   do not print \`checking...' messages
1260       --cache-file=FILE   cache test results in FILE [disabled]
1261   -C, --config-cache      alias for \`--cache-file=config.cache'
1262   -n, --no-create         do not create output files
1263       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1264
1265 Installation directories:
1266   --prefix=PREFIX         install architecture-independent files in PREFIX
1267                           [$ac_default_prefix]
1268   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1269                           [PREFIX]
1270
1271 By default, \`make install' will install all the files in
1272 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1273 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1274 for instance \`--prefix=\$HOME'.
1275
1276 For better control, use the options below.
1277
1278 Fine tuning of the installation directories:
1279   --bindir=DIR           user executables [EPREFIX/bin]
1280   --sbindir=DIR          system admin executables [EPREFIX/sbin]

1334 Some influential environment variables:
1335   CC          C compiler command
1336   CFLAGS      C compiler flags
1337   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1338               nonstandard directory <lib dir>
1339   LIBS        libraries to pass to the linker, e.g. -l<library>
1340   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1341               you have headers in a nonstandard directory <include dir>
1342   CXX         C++ compiler command
1343   CXXFLAGS    C++ compiler flags
1344   XMKMF       Path to xmkmf, Makefile generator for X Window System
1345   CPP         C preprocessor
1346
1347 Use these variables to override the choices made by `configure' or to help
1348 it to find libraries and programs with nonstandard names/locations.

9997    Here is a matrix of mmap possibilities:
9998         mmap private not fixed
9999         mmap private fixed at somewhere currently unmapped
10000         mmap private fixed at somewhere already mapped
10001         mmap shared not fixed
10002         mmap shared fixed at somewhere currently unmapped
10003         mmap shared fixed at somewhere already mapped
10004    For private mappings, we should verify that changes cannot be read()
10005    back from the file, nor mmap's back from the file at a different
10006    address.  (There have been systems where private was not correctly
10007    implemented like the infamous i386 svr4.0, and systems where the
10008    VM page cache was not coherent with the file system buffer cache
10009    like early versions of FreeBSD and possibly contemporary NetBSD.)
10010    For shared mappings, we should conversely verify that changes get
10011    propagated back to all the places they're supposed to be.
10012
10013    Grep wants private fixed already mapped.
10014    The main things grep needs to know about mmap are:
10015    * does it exist and is it safe to write into the mmap'd area
10016    * how to use it (BSD variants)  */
