1.347 -# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
1.348 -#
1.349 -# Of course, Automake must honor this variable whenever it calls a
1.350 -# tool from the auxiliary directory. The problem is that $srcdir (and
1.351 -# therefore $ac_aux_dir as well) can be either absolute or relative,
1.352 -# depending on how configure is run. This is pretty annoying, since
1.353 -# it makes $ac_aux_dir quite unusable in subdirectories: in the top
1.354 -# source directory, any form will work fine, but in subdirectories a
1.355 -# relative path needs to be adjusted first.
1.356 -#
1.357 -# $ac_aux_dir/missing
1.358 -# fails when called from a subdirectory if $ac_aux_dir is relative
1.359 -# $top_srcdir/$ac_aux_dir/missing
1.360 -# fails if $ac_aux_dir is absolute,
1.361 -# fails when called from a subdirectory in a VPATH build with
1.362 -# a relative $ac_aux_dir
1.363 -#
1.364 -# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
1.365 -# are both prefixed by $srcdir. In an in-source build this is usually
1.366 -# harmless because $srcdir is `.', but things will broke when you
1.367 -# start a VPATH build or use an absolute $srcdir.
1.368 -#
1.369 -# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
1.370 -# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
1.371 -# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
1.372 -# and then we would define $MISSING as
1.373 -# MISSING="\${SHELL} $am_aux_dir/missing"
1.374 -# This will work as long as MISSING is not called from configure, because
1.375 -# unfortunately $(top_srcdir) has no meaning in configure.
1.376 -# However there are other variables, like CC, which are often used in
1.377 -# configure, and could therefore not use this "fixed" $ac_aux_dir.
1.378 -#
1.379 -# Another solution, used here, is to always expand $ac_aux_dir to an
1.380 -# absolute PATH. The drawback is that using absolute paths prevent a
1.381 -# configured tree to be moved without reconfiguration.

1.1471 +# harmless because $srcdir is `.', but things will broke when you
1.1472 +# start a VPATH build or use an absolute $srcdir.
1.1473 +#
1.1474 +# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

1.2063 +# created by `make install' are always world readable, even if the

1.2065 +# This was a mistake. There are at least two reasons why we must not
1.2066 +# use `-m 0755':
1.2067 +# - it causes special bits like SGID to be ignored,
1.2068 +# - it may be too restrictive (some setups expect 775 directories).
1.2069 +#

1.2071 +# setting umask.

1.2074 +# Some implementations (such as Solaris 8's) are not thread-safe: if a
