This is pretty annoying, since 517# it makes $ac_aux_dir quite unusable in subdirectories: in the top 518# source directory, any form will work fine, but in subdirectories a 519# relative path needs to be adjusted first. 520# 521# $ac_aux_dir/missing 522# fails when called from a subdirectory if $ac_aux_dir is relative 523# $top_srcdir/$ac_aux_dir/missing 524# fails if $ac_aux_dir is absolute, 525# fails when called from a subdirectory in a VPATH build with 526# a relative $ac_aux_dir 527# 528# The reason of the latter failure is that $top_srcdir and $ac_aux_dir 529# are both prefixed by $srcdir. In an in-source build this is usually 530# harmless because $srcdir is '.', but things will broke when you 531# start a VPATH build or use an absolute $srcdir. 532# 533# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, 534# iff we strip the leading $srcdir from $ac_aux_dir. That would be: 535# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` 536# and then we would define $MISSING as 537# MISSING="\${SHELL} $am_aux_dir/missing" 538# This will work as long as MISSING is not called from configure, because 539# unfortunately $(top_srcdir) has no meaning in configure. 540# However there are other variables, like CC, which are often used in 541# configure, and could therefore not use this "fixed" $ac_aux_dir. 542# 543# Another solution, used here, is to always expand $ac_aux_dir to an 544# absolute PATH.
