 225 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
 226 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
 227 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
 228 #
 229 # Of course, Automake must honor this variable whenever it calls a
 230 # tool from the auxiliary directory.  The problem is that $srcdir (and
 231 # therefore $ac_aux_dir as well) can be either absolute or relative,
 232 # depending on how configure is run.  This is pretty annoying, since
 233 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
 234 # source directory, any form will work fine, but in subdirectories a
 235 # relative path needs to be adjusted first.
 236 #
 237 # $ac_aux_dir/missing
 238 #    fails when called from a subdirectory if $ac_aux_dir is relative
 239 # $top_srcdir/$ac_aux_dir/missing
 240 #    fails if $ac_aux_dir is absolute,
 241 #    fails when called from a subdirectory in a VPATH build with
 242 #          a relative $ac_aux_dir
 243 #
 244 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
 245 # are both prefixed by $srcdir.  In an in-source build this is usually
 246 # harmless because $srcdir is `.', but things will broke when you
 247 # start a VPATH build or use an absolute $srcdir.
 248 #
 249 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
 250 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
 251 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
 252 # and then we would define $MISSING as
 253 #   MISSING="\${SHELL} $am_aux_dir/missing"
 254 # This will work as long as MISSING is not called from configure, because
 255 # unfortunately $(top_srcdir) has no meaning in configure.
 256 # However there are other variables, like CC, which are often used in
 257 # configure, and could therefore not use this "fixed" $ac_aux_dir.
 258 #
 259 # Another solution, used here, is to always expand $ac_aux_dir to an
 260 # absolute PATH.  The drawback is that using absolute paths prevent a
 261 # configured tree to be moved without reconfiguration.

1178 dnl    $(top_builddir)/intl/libintl.a will be created.

1180 dnl    implementations (in libc or libintl) without the ngettext() function
1181 dnl    will be ignored.
1182 dnl LIBDIR is used to find the intl libraries.  If empty,
