# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
371
# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
372
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
373
#
374
# Of course, Automake must honor this variable whenever it calls a
375
# tool from the auxiliary directory.  The problem is that $srcdir (and
376
# therefore $ac_aux_dir as well) can be either absolute or relative,
377
# depending on how configure is run.  This is pretty annoying, since
378
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
379
# source directory, any form will work fine, but in subdirectories a
380
# relative path needs to be adjusted first.
381
#
382
# $ac_aux_dir/missing
383
#    fails when called from a subdirectory if $ac_aux_dir is relative
384
# $top_srcdir/$ac_aux_dir/missing
385
#    fails if $ac_aux_dir is absolute,
386
#    fails when called from a subdirectory in a VPATH build with
387
#          a relative $ac_aux_dir
388
#
389
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
390
# are both prefixed by $srcdir.  In an in-source build this is usually
391
# harmless because $srcdir is `.', but things will broke when you
392
# start a VPATH build or use an absolute $srcdir.
393
#
394
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
395
# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
396
#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
397
# and then we would define $MISSING as
398
#   MISSING="\${SHELL} $am_aux_dir/missing"
399
# This will work as long as MISSING is not called from configure, because
400
# unfortunately $(top_srcdir) has no meaning in configure.
401
# However there are other variables, like CC, which are often used in
402
# configure, and could therefore not use this "fixed" $ac_aux_dir.
403
#
404
# Another solution, used here, is to always expand $ac_aux_dir to an
405
# absolute PATH.  The drawback is that using absolute paths prevent a
406
# configured tree to be moved without reconfiguration.
