meillo@36 228 # Of course, Automake must honor this variable whenever it calls a

meillo@36 231 # depending on how configure is run. This is pretty annoying, since
meillo@36 232 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
meillo@36 233 # source directory, any form will work fine, but in subdirectories a

meillo@36 241 # a relative $ac_aux_dir
meillo@36 242 #
meillo@36 243 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
meillo@36 244 # are both prefixed by $srcdir. In an in-source build this is usually
meillo@36 245 # harmless because $srcdir is `.', but things will broke when you
meillo@36 246 # start a VPATH build or use an absolute $srcdir.
meillo@36 247 #
meillo@36 248 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
meillo@36 249 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
meillo@36 250 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`

meillo@36 254 # unfortunately $(top_srcdir) has no meaning in configure.
