411# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets

413# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
414#
415# Of course, Automake must honor this variable whenever it calls a
416# tool from the auxiliary directory.  The problem is that $srcdir (and
417# therefore $ac_aux_dir as well) can be either absolute or relative,
418# depending on how configure is run.  This is pretty annoying, since
419# it makes $ac_aux_dir quite unusable in subdirectories: in the top
420# source directory, any form will work fine, but in subdirectories a
421# relative path needs to be adjusted first.
422#
423# $ac_aux_dir/missing
424#    fails when called from a subdirectory if $ac_aux_dir is relative
425# $top_srcdir/$ac_aux_dir/missing
426#    fails if $ac_aux_dir is absolute,
427#    fails when called from a subdirectory in a VPATH build with
428#          a relative $ac_aux_dir
429#
430# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
431# are both prefixed by $srcdir.  In an in-source build this is usually
432# harmless because $srcdir is '.', but things will broke when you
433# start a VPATH build or use an absolute $srcdir.
434#
435# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
436# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
437#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
438# and then we would define $MISSING as
439#   MISSING="\${SHELL} $am_aux_dir/missing"
440# This will work as long as MISSING is not called from configure, because
441# unfortunately $(top_srcdir) has no meaning in configure.
442# However there are other variables, like CC, which are often used in
443# configure, and could therefore not use this "fixed" $ac_aux_dir.

881Your 'rm' program seems unable to run without file operands specified
882on the command line, even when the '-f' option is present.  This is contrary

884the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
885
886Please tell bug-automake@gnu.org about your system, including the value
887of your $PATH and any error possibly output before this message.  This
