890# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
891# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
892# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
893#
894# Of course, Automake must honor this variable whenever it calls a
895# tool from the auxiliary directory. The problem is that $srcdir (and
896# therefore $ac_aux_dir as well) can be either absolute or relative,
897# depending on how configure is run. This is pretty annoying, since
898# it makes $ac_aux_dir quite unusable in subdirectories: in the top
899# source directory, any form will work fine, but in subdirectories a
900# relative path needs to be adjusted first.
901#
902# $ac_aux_dir/missing
903# fails when called from a subdirectory if $ac_aux_dir is relative
904# $top_srcdir/$ac_aux_dir/missing
905# fails if $ac_aux_dir is absolute,
906# fails when called from a subdirectory in a VPATH build with
907# a relative $ac_aux_dir
908#
909# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
910# are both prefixed by $srcdir. In an in-source build this is usually
911# harmless because $srcdir is `.', but things will broke when you
912# start a VPATH build or use an absolute $srcdir.
913#
914# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
915# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
916# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
917# and then we would define $MISSING as
918# MISSING="\${SHELL} $am_aux_dir/missing"
919# This will work as long as MISSING is not called from configure, because
920# unfortunately $(top_srcdir) has no meaning in configure.
921# However there are other variables, like CC, which are often used in
922# configure, and could therefore not use this "fixed" $ac_aux_dir.
923#
924# Another solution, used here, is to always expand $ac_aux_dir to an
925# absolute PATH. The drawback is that using absolute paths prevent a
926# configured tree to be moved without reconfiguration.
