2241 # Of course, Automake must honor this variable whenever it calls a

2243 # therefore $ac_aux_dir as well) can be either absolute or relative,
2244 # depending on how configure is run. This is pretty annoying, since
2245 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
2246 # source directory, any form will work fine, but in subdirectories a
2247 # relative path needs to be adjusted first.

2253 # fails when called from a subdirectory in a VPATH build with
2254 # a relative $ac_aux_dir
2256 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
2257 # are both prefixed by $srcdir. In an in-source build this is usually
2258 # harmless because $srcdir is `.', but things will broke when you
2259 # start a VPATH build or use an absolute $srcdir.
2261 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
2262 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
2263 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
2264 # and then we would define $MISSING as

2266 # This will work as long as MISSING is not called from configure, because
