  72 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
  73 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
  74 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
  75 #
  76 # Of course, Automake must honor this variable whenever it calls a
  77 # tool from the auxiliary directory.  The problem is that $srcdir (and
  78 # therefore $ac_aux_dir as well) can be either absolute or relative,
  79 # depending on how configure is run.  This is pretty annoying, since
  80 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  81 # source directory, any form will work fine, but in subdirectories a
  82 # relative path needs to be adjusted first.
  83 #
  84 # $ac_aux_dir/missing
  85 #    fails when called from a subdirectory if $ac_aux_dir is relative
  86 # $top_srcdir/$ac_aux_dir/missing
  87 #    fails if $ac_aux_dir is absolute,
  88 #    fails when called from a subdirectory in a VPATH build with
  89 #          a relative $ac_aux_dir
  90 #
  91 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  92 # are both prefixed by $srcdir.  In an in-source build this is usually
  93 # harmless because $srcdir is `.', but things will broke when you
  94 # start a VPATH build or use an absolute $srcdir.
  95 #
  96 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  97 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
  98 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
  99 # and then we would define $MISSING as
 100 #   MISSING="\${SHELL} $am_aux_dir/missing"
 101 # This will work as long as MISSING is not called from configure, because
 102 # unfortunately $(top_srcdir) has no meaning in configure.
 103 # However there are other variables, like CC, which are often used in
 104 # configure, and could therefore not use this "fixed" $ac_aux_dir.
 105 #
 106 # Another solution, used here, is to always expand $ac_aux_dir to an
 107 # absolute PATH.  The drawback is that using absolute paths prevent a
 108 # configured tree to be moved without reconfiguration.

 865 # AM_PROG_INSTALL_STRIP
 866 # ---------------------
 867 # One issue with vendor `install' (even GNU) is that you can't
 868 # specify the program used to strip binaries.  This is especially
 869 # annoying in cross-compiling environments, where the build's strip
 870 # is unlikely to handle the host's binaries.
 871 # Fortunately install-sh will honor a STRIPPROG variable, so we
 872 # always use install-sh in `make install-strip', and initialize
 873 # STRIPPROG with the value of the STRIP variable (set by the user).
 874 AC_DEFUN([AM_PROG_INSTALL_STRIP],
 875 [AC_REQUIRE([AM_PROG_INSTALL_SH])dnl
 876 # Installed binaries are usually stripped using `strip' when the user
 877 # run `make install-strip'.  However `strip' might not be the right
 878 # tool to use in cross-compilation environments, therefore Automake
 879 # will honor the `STRIP' environment variable to overrule this program.
