  346 #
  347 # Of course, Automake must honor this variable whenever it calls a

  349 # therefore $ac_aux_dir as well) can be either absolute or relative,
  350 # depending on how configure is run.  This is pretty annoying, since
  351 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  352 # source directory, any form will work fine, but in subdirectories a
  353 # relative path needs to be adjusted first.

  360 #          a relative $ac_aux_dir
  361 #
  362 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  363 # are both prefixed by $srcdir.  In an in-source build this is usually
  364 # harmless because $srcdir is '.', but things will broke when you
  365 # start a VPATH build or use an absolute $srcdir.
  366 #
  367 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  368 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
  369 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
  370 # and then we would define $MISSING as

  374 # However there are other variables, like CC, which are often used in
  375 # configure, and could therefore not use this "fixed" $ac_aux_dir.
  376 #

  822 
  823 Your 'rm' program seems unable to run without file operands specified
  824 on the command line, even when the '-f' option is present.  This is contrary
  825 to the behaviour of most rm programs out there, and not conforming with
  826 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
  827

  829 of your $PATH and any error possibly output before this message.  This

 1258 # ---------------------
 1259 # One issue with vendor 'install' (even GNU) is that you can't
 1260 # specify the program used to strip binaries.  This is especially
 1261 # annoying in cross-compiling environments, where the build's strip
 1262 # is unlikely to handle the host's binaries.
 1263 # Fortunately install-sh will honor a STRIPPROG variable, so we
 1264 # always use install-sh in "make install-strip", and initialize
 1265 # STRIPPROG with the value of the STRIP variable (set by the user).
