   41 dnl with the API version to also check the API compatibility. Example:
   42 dnl a MINIMUN-VERSION of 1:1.2.5 won't pass the test unless the installed
   43 dnl version of libgcrypt is at least 1.2.5 *and* the API number is 1.  Using

  211 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
  212 # $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
  213 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
  214 #
  215 # Of course, Automake must honor this variable whenever it calls a
  216 # tool from the auxiliary directory.  The problem is that $srcdir (and
  217 # therefore $ac_aux_dir as well) can be either absolute or relative,
  218 # depending on how configure is run.  This is pretty annoying, since
  219 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  220 # source directory, any form will work fine, but in subdirectories a
  221 # relative path needs to be adjusted first.
  222 #
  223 # $ac_aux_dir/missing
  224 #    fails when called from a subdirectory if $ac_aux_dir is relative
  225 # $top_srcdir/$ac_aux_dir/missing
  226 #    fails if $ac_aux_dir is absolute,
  227 #    fails when called from a subdirectory in a VPATH build with
  228 #          a relative $ac_aux_dir
  229 #
  230 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  231 # are both prefixed by $srcdir.  In an in-source build this is usually
  232 # harmless because $srcdir is '.', but things will broke when you
  233 # start a VPATH build or use an absolute $srcdir.
  234 #
  235 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  236 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
  237 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
  238 # and then we would define $MISSING as
  239 #   MISSING="\${SHELL} $am_aux_dir/missing"
  240 # This will work as long as MISSING is not called from configure, because
  241 # unfortunately $(top_srcdir) has no meaning in configure.
  242 # However there are other variables, like CC, which are often used in
  243 # configure, and could therefore not use this "fixed" $ac_aux_dir.
  244 #
  245 # Another solution, used here, is to always expand $ac_aux_dir to an
  246 # absolute PATH.  The drawback is that using absolute paths prevent a
  247 # configured tree to be moved without reconfiguration.
