 # This file is free software; the Free Software Foundation

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

 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to

 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.

 #

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

 # tool from the auxiliary directory.  The problem is that $srcdir (and

 # therefore $ac_aux_dir as well) can be either absolute or relative,

 # depending on how configure is run.  This is pretty annoying, since

 # it makes $ac_aux_dir quite unusable in subdirectories: in the top

 # source directory, any form will work fine, but in subdirectories a

 # relative path needs to be adjusted first.

 #

 # $ac_aux_dir/missing

 #    fails when called from a subdirectory if $ac_aux_dir is relative

 # $top_srcdir/$ac_aux_dir/missing

 #    fails if $ac_aux_dir is absolute,

 #    fails when called from a subdirectory in a VPATH build with

 #          a relative $ac_aux_dir

 #

 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir

 # are both prefixed by $srcdir.  In an in-source build this is usually

 # harmless because $srcdir is `.', but things will broke when you

 # start a VPATH build or use an absolute $srcdir.

 #

 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:

 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`

 # and then we would define $MISSING as

 #   MISSING="\${SHELL} $am_aux_dir/missing"

 # This will work as long as MISSING is not called from configure, because

 # unfortunately $(top_srcdir) has no meaning in configure.

 # However there are other variables, like CC, which are often used in

 # configure, and could therefore not use this "fixed" $ac_aux_dir.

 #

 # Another solution, used here, is to always expand $ac_aux_dir to an

 # absolute PATH.  The drawback is that using absolute paths prevent a

 # configured tree to be moved without reconfiguration.

 # AM_PROG_MKDIR_P

 # ---------------

 # Check whether `mkdir -p' is supported, fallback to mkinstalldirs otherwise.

 #

 # Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories

 # created by `make install' are always world readable, even if the

 # installer happens to have an overly restrictive umask (e.g. 077).

 # This was a mistake.  There are at least two reasons why we must not

 # use `-m 0755':

 #   - it causes special bits like SGID to be ignored,

 #   - it may be too restrictive (some setups expect 775 directories).

 #

 # Do not use -m 0755 and let people choose whatever they expect by

 # setting umask.

 #

 # We cannot accept any implementation of `mkdir' that recognizes `-p'.

 # Some implementations (such as Solaris 8's) are not thread-safe: if a

 # parallel make tries to run `mkdir -p a/b' and `mkdir -p a/c'

 # concurrently, both version can detect that a/ is missing, but only

 # one can create it and the other will error out.  Consequently we

 # restrict ourselves to GNU make (using the --version option ensures

 # this.)

   # for two reasons:

   #  1. if the package is installed by a user who cannot write `.'

   #     make install will fail,

   #  2. the above comment should most certainly read

   #     $(mkdir_p) $(DESTDIR)$(somedir)

   #     so it does not work when $(somedir) is undefined and

   #  To support the latter case, we have to write
