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

1146 dnl Usage: AM_WITH_NLS([TOOLSYMBOL], [NEEDSYMBOL], [LIBDIR]).
1147 dnl If TOOLSYMBOL is specified and is 'use-libtool', then a libtool library
1148 dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
1149 dnl    depending on --{enable,disable}-{shared,static} and on the presence of
1150 dnl    AM-DISABLE-SHARED). Otherwise, a static library
1151 dnl    $(top_builddir)/intl/libintl.a will be created.
1152 dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
1153 dnl    implementations (in libc or libintl) without the ngettext() function
1154 dnl    will be ignored.
1155 dnl LIBDIR is used to find the intl libraries.  If empty,
1156 dnl    the value `$(top_builddir)/intl/' is used.
1157 dnl
1158 dnl The result of the configuration is one of three cases:
1159 dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
1160 dnl    and used.
1161 dnl    Catalog format: GNU --> install in $(datadir)
1162 dnl    Catalog extension: .mo after installation, .gmo in source tree
1163 dnl 2) GNU gettext has been found in the system's C library.
1164 dnl    Catalog format: GNU --> install in $(datadir)
1165 dnl    Catalog extension: .mo after installation, .gmo in source tree
1166 dnl 3) No internationalization, always use English msgid.
1167 dnl    Catalog format: none
1168 dnl    Catalog extension: none
1169 dnl The use of .gmo is historical (it was needed to avoid overwriting the
1170 dnl GNU format catalogs when building on a platform with an X/Open gettext),
1171 dnl but we keep it in order not to force irrelevant filename changes on the
