515 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
516 # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
517 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
519 # Of course, Automake must honor this variable whenever it calls a
520 # tool from the auxiliary directory. The problem is that $srcdir (and
521 # therefore $ac_aux_dir as well) can be either absolute or relative,
522 # depending on how configure is run. This is pretty annoying, since
523 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
524 # source directory, any form will work fine, but in subdirectories a
525 # relative path needs to be adjusted first.
527 # $ac_aux_dir/missing
528 # fails when called from a subdirectory if $ac_aux_dir is relative
529 # $top_srcdir/$ac_aux_dir/missing
530 # fails if $ac_aux_dir is absolute,
531 # fails when called from a subdirectory in a VPATH build with
532 # a relative $ac_aux_dir
534 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
535 # are both prefixed by $srcdir. In an in-source build this is usually
536 # harmless because $srcdir is `.', but things will broke when you
537 # start a VPATH build or use an absolute $srcdir.
539 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
540 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
541 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
542 # and then we would define $MISSING as
543 # MISSING="\${SHELL} $am_aux_dir/missing"
544 # This will work as long as MISSING is not called from configure, because
545 # unfortunately $(top_srcdir) has no meaning in configure.
546 # However there are other variables, like CC, which are often used in
547 # configure, and could therefore not use this "fixed" $ac_aux_dir.
549 # Another solution, used here, is to always expand $ac_aux_dir to an

1249 # ---------------------

1251 # specify the program used to strip binaries. This is especially
1252 # annoying in cross-compiling environments, where the build's strip
1253 # is unlikely to handle the host's binaries.
1254 # Fortunately install-sh will honor a STRIPPROG variable, so we
1255 # always use install-sh in `make install-strip', and initialize
1256 # STRIPPROG with the value of the STRIP variable (set by the user).
