371 # Of course, Automake must honor this variable whenever it calls a

373 # therefore $ac_aux_dir as well) can be either absolute or relative,
374 # depending on how configure is run. This is pretty annoying, since
375 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
376 # source directory, any form will work fine, but in subdirectories a
377 # relative path needs to be adjusted first.

382 # fails if $ac_aux_dir is absolute,
383 # fails when called from a subdirectory in a VPATH build with
384 # a relative $ac_aux_dir
386 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
387 # are both prefixed by $srcdir. In an in-source build this is usually
388 # harmless because $srcdir is `.', but things will broke when you
389 # start a VPATH build or use an absolute $srcdir.
391 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
392 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
393 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
394 # and then we would define $MISSING as
395 # MISSING="\${SHELL} $am_aux_dir/missing"
396 # This will work as long as MISSING is not called from configure, because
397 # unfortunately $(top_srcdir) has no meaning in configure.
398 # However there are other variables, like CC, which are often used in
399 # configure, and could therefore not use this "fixed" $ac_aux_dir.

1464 # be used in projects which are not available under the GNU General Public

1474 dnl Usage: MUTT_AM_WITH_NLS([TOOLSYMBOL], [NEEDSYMBOL], [LIBDIR]).
1475 dnl If TOOLSYMBOL is specified and is 'use-libtool', then a libtool library
1476 dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
1477 dnl depending on --{enable,disable}-{shared,static} and on the presence of
1478 dnl AM-DISABLE-SHARED). Otherwise, a static library
1479 dnl $(top_builddir)/intl/libintl.a will be created.
1480 dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
1481 dnl implementations (in libc or libintl) without the ngettext() function
1482 dnl will be ignored.
1483 dnl LIBDIR is used to find the intl libraries. If empty,
1484 dnl the value `$(top_builddir)/intl/' is used.
1486 dnl The result of the configuration is one of three cases:
1487 dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
1489 dnl Catalog format: GNU --> install in $(datadir)
1490 dnl Catalog extension: .mo after installation, .gmo in source tree
1491 dnl 2) GNU gettext has been found in the system's C library.
1492 dnl Catalog format: GNU --> install in $(datadir)
1493 dnl Catalog extension: .mo after installation, .gmo in source tree
1494 dnl 3) No internationalization, always use English msgid.
1495 dnl Catalog format: none
1496 dnl Catalog extension: none
1497 dnl The use of .gmo is historical (it was needed to avoid overwriting the
