Another problem is what to do with the second argument of AM_GNU_GETTEXT.

Question to the autoconf experts: Is it possible to write a macro
AM_GETTEXT_NEED_NGETTEXT such that whenever a user writes
   AM_GETTEXT_NEED_NGETTEXT
   AM_GNU_GETTEXT
or
   AM_GNU_GETTEXT
   AM_GETTEXT_NEED_NGETTEXT

exists elsewhere? So, a kind of "backward propagation"?

the AM_GNU_GETTEXT macro "knows" that a AM_GETTEXT_NEED_NGETTEXT invocation

Untested:

m4_define([gt__NEED_NGETTEXT_FU],
[shell code to execute after expansion of AM_GNU_GETTEXT,
 whenever AM_GETTEXT_NEED_NGETTEXT is present somewhere])

AC_DEFUN([AM_GNU_GETTEXT],
[
...current contents of AM_GNU_GETTEXT definition...

dnl make sure gt__NEED_NGETTEXT_FU is always expanded in the
dnl presence of AM_GETTEXT_NEED_NGETTEXT:
AC_PROVIDE_IFELSE([AM_GETTEXT_NEED_NGETTEXT],
        [gt__NEED_NGETTEXT_FU],
  [m4_define([AM_GETTEXT_NEED_NGETTEXT],
    [defn([AM_GETTEXT_NEED_NGETTEXT])
    gt__NEED_NGETTEXT_FU
  ])dnl
])# AM_GNU_GETTEXT

Cheers,
        Gary.
