2090 # depending on how configure is run. This is pretty annoying, since
2091 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
2092 # source directory, any form will work fine, but in subdirectories a
2093 # relative path needs to be adjusted first.

2098 # fails if $ac_aux_dir is absolute,
2099 # fails when called from a subdirectory in a VPATH build with
2100 # a relative $ac_aux_dir
2102 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
2103 # are both prefixed by $srcdir. In an in-source build this is usually
2104 # harmless because $srcdir is `.', but things will broke when you
2105 # start a VPATH build or use an absolute $srcdir.
2107 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
2108 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
2109 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
2110 # and then we would define $MISSING as
2111 # MISSING="\${SHELL} $am_aux_dir/missing"
2112 # This will work as long as MISSING is not called from configure, because
2113 # unfortunately $(top_srcdir) has no meaning in configure.
2114 # However there are other variables, like CC, which are often used in
2115 # configure, and could therefore not use this "fixed" $ac_aux_dir.
