 \`configure' configures c-ares 1.34.5 to adapt to many kinds of systems.
 
 Usage: $0 [OPTION]... [VAR=VALUE]...
 
 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 VAR=VALUE.  See below for descriptions of some of the useful variables.
 
 Defaults for the options are specified in brackets.
 
 Configuration:
   -h, --help              display this help and exit
       --help=short        display options specific to this package
       --help=recursive    display the short help of all the included packages
   -V, --version           display version information and exit
   -q, --quiet, --silent   do not print \`checking ...' messages
       --cache-file=FILE   cache test results in FILE [disabled]
   -C, --config-cache      alias for \`--cache-file=config.cache'
   -n, --no-create         do not create output files
       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
 
 Installation directories:
   --prefix=PREFIX         install architecture-independent files in PREFIX
                           [$ac_default_prefix]
   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                           [PREFIX]
 
 By default, \`make install' will install all the files in
 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 for instance \`--prefix=\$HOME'.
 
 For better control, use the options below.
 
 Fine tuning of the installation directories:
   --bindir=DIR            user executables [EPREFIX/bin]
   --sbindir=DIR           system admin executables [EPREFIX/sbin]
   --libexecdir=DIR        program executables [EPREFIX/libexec]

   --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
   --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
   --libdir=DIR            object code libraries [EPREFIX/lib]
   --includedir=DIR        C header files [PREFIX/include]
   --oldincludedir=DIR     C header files for non-gcc [/usr/include]
   --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
   --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
   --infodir=DIR           info documentation [DATAROOTDIR/info]
   --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]

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

 Aborting the configuration process, to ensure you take notice of the issue.
 
 You can download and install GNU coreutils to get an 'rm' implementation
 that behaves properly: <https://www.gnu.org/software/coreutils/>.
 
 If you want to complete the configuration process using your problematic
 'rm' anyway, export the environment variable ACCEPT_INFERIOR_RM_PROGRAM
 to "yes", and re-run configure.
