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.
