[bug-gettext] AC_CONFIG_MACRO_DIR{,S} & ACLOCAL_AMFLAGS

[Pavel Raiskup]

Hello,

I have noticed that GNU gettext is unable to recognize the
AC_CONFIG_MACRO_DIR & AC_CONFIG_MACRO_DIRS macros in configure.ac.
Gettextize seem to consider just the ACLOCAL_AMFLAGS as the construct
specifiing where to put local m4s.

Relevant automake's discussion:

  .. it continues here:
  http://lists.gnu.org/archive/html/bug-automake/2013-02/msg00014.html

Many projects started to use AC_CONFIG_MACRO_DIR inside configure.ac but
it is then missed by gettextize.  When there is specified something like

  AC_CONFIG_MACRO_DIRS([some_different_place_than_m4])

(and the ACLOCAL_AMFLAGS unspecified) gettextize still uses the 'm4'
directory as place to put macros.  The problem is that aclocal then does
not look for m4s files 'm4' (because the name 'm4' is not defined as
something like default place where copy macros into).
