328 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
330 # Of course, Automake must honor this variable whenever it calls a
331 # tool from the auxiliary directory. The problem is that $srcdir (and
332 # therefore $ac_aux_dir as well) can be either absolute or relative,
333 # depending on how configure is run. This is pretty annoying, since
334 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
335 # source directory, any form will work fine, but in subdirectories a
336 # relative path needs to be adjusted first.
338 # $ac_aux_dir/missing
339 # fails when called from a subdirectory if $ac_aux_dir is relative
340 # $top_srcdir/$ac_aux_dir/missing
341 # fails if $ac_aux_dir is absolute,
342 # fails when called from a subdirectory in a VPATH build with
343 # a relative $ac_aux_dir
345 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
346 # are both prefixed by $srcdir. In an in-source build this is usually
347 # harmless because $srcdir is '.', but things will broke when you
348 # start a VPATH build or use an absolute $srcdir.
350 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
351 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
352 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
353 # and then we would define $MISSING as
354 # MISSING="\${SHELL} $am_aux_dir/missing"
355 # This will work as long as MISSING is not called from configure, because
356 # unfortunately $(top_srcdir) has no meaning in configure.
357 # However there are other variables, like CC, which are often used in
358 # configure, and could therefore not use this "fixed" $ac_aux_dir.

1196 # is unlikely to handle the host's binaries.
1197 # Fortunately install-sh will honor a STRIPPROG variable, so we
1198 # always use install-sh in "make install-strip", and initialize
1199 # STRIPPROG with the value of the STRIP variable (set by the user).
