2342c393a42Smrg# Of course, Automake must honor this variable whenever it calls a

2362c393a42Smrg# therefore $ac_aux_dir as well) can be either absolute or relative,
2372c393a42Smrg# depending on how configure is run.  This is pretty annoying, since
2382c393a42Smrg# it makes $ac_aux_dir quite unusable in subdirectories: in the top
2392c393a42Smrg# source directory, any form will work fine, but in subdirectories a
2402c393a42Smrg# relative path needs to be adjusted first.

2472c393a42Smrg#          a relative $ac_aux_dir
2482c393a42Smrg#
2492c393a42Smrg# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
2502c393a42Smrg# are both prefixed by $srcdir.  In an in-source build this is usually
2512c393a42Smrg# harmless because $srcdir is `.', but things will broke when you
2522c393a42Smrg# start a VPATH build or use an absolute $srcdir.
2532c393a42Smrg#
2542c393a42Smrg# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
2552c393a42Smrg# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
2562c393a42Smrg#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
2572c393a42Smrg# and then we would define $MISSING as
2582c393a42Smrg#   MISSING="\${SHELL} $am_aux_dir/missing"
2592c393a42Smrg# This will work as long as MISSING is not called from configure, because
2602c393a42Smrg# unfortunately $(top_srcdir) has no meaning in configure.
2612c393a42Smrg# However there are other variables, like CC, which are often used in
2622c393a42Smrg# configure, and could therefore not use this "fixed" $ac_aux_dir.
2632c393a42Smrg#
2642c393a42Smrg# Another solution, used here, is to always expand $ac_aux_dir to an
