287 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
288 # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
289 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
291 # Of course, Automake must honor this variable whenever it calls a
292 # tool from the auxiliary directory. The problem is that $srcdir (and
293 # therefore $ac_aux_dir as well) can be either absolute or relative,
294 # depending on how configure is run. This is pretty annoying, since
295 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
296 # source directory, any form will work fine, but in subdirectories a
297 # relative path needs to be adjusted first.
299 # $ac_aux_dir/missing
300 # fails when called from a subdirectory if $ac_aux_dir is relative
301 # $top_srcdir/$ac_aux_dir/missing
302 # fails if $ac_aux_dir is absolute,
303 # fails when called from a subdirectory in a VPATH build with
304 # a relative $ac_aux_dir
306 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
307 # are both prefixed by $srcdir. In an in-source build this is usually
308 # harmless because $srcdir is '.', but things will broke when you
309 # start a VPATH build or use an absolute $srcdir.
311 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
312 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
313 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
314 # and then we would define $MISSING as
315 # MISSING="\${SHELL} $am_aux_dir/missing"
316 # This will work as long as MISSING is not called from configure, because
317 # unfortunately $(top_srcdir) has no meaning in configure.
318 # However there are other variables, like CC, which are often used in
319 # configure, and could therefore not use this "fixed" $ac_aux_dir.
321 # Another solution, used here, is to always expand $ac_aux_dir to an

1199 # ---------------------
1200 # One issue with vendor 'install' (even GNU) is that you can't
1201 # specify the program used to strip binaries. This is especially
1202 # annoying in cross-compiling environments, where the build's strip
1203 # is unlikely to handle the host's binaries.
1204 # Fortunately install-sh will honor a STRIPPROG variable, so we
1205 # always use install-sh in "make install-strip", and initialize
1206 # STRIPPROG with the value of the STRIP variable (set by the user).
