 1347 \`configure' configures memcached 1.6.15 to adapt to many kinds of systems.
 1348 
 1349 Usage: $0 [OPTION]... [VAR=VALUE]...
 1350 
 1351 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 1352 VAR=VALUE.  See below for descriptions of some of the useful variables.
 1353 
 1354 Defaults for the options are specified in brackets.
 1355 
 1356 Configuration:
 1357   -h, --help              display this help and exit
 1358       --help=short        display options specific to this package
 1359       --help=recursive    display the short help of all the included packages
 1360   -V, --version           display version information and exit
 1361   -q, --quiet, --silent   do not print \`checking ...' messages
 1362       --cache-file=FILE   cache test results in FILE [disabled]
 1363   -C, --config-cache      alias for \`--cache-file=config.cache'
 1364   -n, --no-create         do not create output files
 1365       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
 1366 
 1367 Installation directories:
 1368   --prefix=PREFIX         install architecture-independent files in PREFIX
 1369                           [$ac_default_prefix]
 1370   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
 1371                           [PREFIX]
 1372 
 1373 By default, \`make install' will install all the files in
 1374 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 1375 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 1376 for instance \`--prefix=\$HOME'.
 1377 
 1378 For better control, use the options below.
 1379 
 1380 Fine tuning of the installation directories:
 1381   --bindir=DIR            user executables [EPREFIX/bin]

 1453 Some influential environment variables:
 1454   CC          C compiler command
 1455   CFLAGS      C compiler flags
 1456   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 1457               nonstandard directory <lib dir>
 1458   LIBS        libraries to pass to the linker, e.g. -l<library>
 1459   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
 1460               you have headers in a nonstandard directory <include dir>
 1461   CPP         C preprocessor
 1462 
 1463 Use these variables to override the choices made by `configure' or to help
 1464 it to find libraries and programs with nonstandard names/locations.

 3186 Oops!
 3187 
 3188 Your 'rm' program seems unable to run without file operands specified
 3189 on the command line, even when the '-f' option is present.  This is contrary
 3190 to the behaviour of most rm programs out there, and not conforming with
 3191 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
 3192 
 3193 Please tell bug-automake@gnu.org about your system, including the value
 3194 of your $PATH and any error possibly output before this message.  This
 3195 can help us improve future automake versions.
