# 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.
