 1227 \`configure' configures bwping 1.17 to adapt to many kinds of systems.
 1228 
 1229 Usage: $0 [OPTION]... [VAR=VALUE]...
 1230 
 1231 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 1232 VAR=VALUE.  See below for descriptions of some of the useful variables.
 1233 
 1234 Defaults for the options are specified in brackets.
 1235 
 1236 Configuration:
 1237   -h, --help              display this help and exit
 1238       --help=short        display options specific to this package
 1239       --help=recursive    display the short help of all the included packages
 1240   -V, --version           display version information and exit
 1241   -q, --quiet, --silent   do not print \`checking ...' messages
 1242       --cache-file=FILE   cache test results in FILE [disabled]
 1243   -C, --config-cache      alias for \`--cache-file=config.cache'
 1244   -n, --no-create         do not create output files
 1245       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
 1246 
 1247 Installation directories:
 1248   --prefix=PREFIX         install architecture-independent files in PREFIX
 1249                           [$ac_default_prefix]
 1250   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
 1251                           [PREFIX]
 1252 
 1253 By default, \`make install' will install all the files in
 1254 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 1255 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 1256 for instance \`--prefix=\$HOME'.
 1257 
 1258 For better control, use the options below.

 1308 Some influential environment variables:
 1309   CC          C compiler command
 1310   CFLAGS      C compiler flags
 1311   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 1312               nonstandard directory <lib dir>
 1313   LIBS        libraries to pass to the linker, e.g. -l<library>
 1314   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
 1315               you have headers in a nonstandard directory <include dir>
 1316 
 1317 Use these variables to override the choices made by `configure' or to help
 1318 it to find libraries and programs with nonstandard names/locations.

 2449 on the command line, even when the '-f' option is present.  This is contrary
 2450 to the behaviour of most rm programs out there, and not conforming with
 2451 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
 2452 
 2453 Please tell bug-automake@gnu.org about your system, including the value
 2454 of your $PATH and any error possibly output before this message.  This
