 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: <http://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.

 /* alloca.c -- allocate automatically reclaimed memory
   (Mostly) portable public-domain implementation -- D A Gwyn
   This implementation of the PWB library alloca function,
   which is used to allocate space off the run-time stack so
   that it is automatically reclaimed upon procedure exit,
   was inspired by discussions with J. Q. Johnson of Cornell.
   J.Otto Tennant <jot@cray.com> contributed the Cray support.
   There are some preprocessor constants that can
   be defined when compiling for your specific system, for
   improved efficiency; however, the defaults should be okay.
   The general concept of this implementation is to keep
   track of all alloca-allocated blocks, and reclaim any
   that are found to be deeper in the stack than the current
   invocation.  This heuristic does not reclaim storage as
   soon as it becomes invalid, but it will do so eventually.
   As a special case, alloca(0) reclaims storage without
   allocating any.  It is a good idea to use alloca(0) in
   your main control loop, etc. to force garbage collection.  */
