Problem with gettext on Solaris

[Brian Cameron]

The AM_GNU_GETTEXT macro fails on Solaris even though Solaris has been made
compatible with GNU gettext.  AM_GNU_GETTEXT always wants to build the
gettext sources included with various modules.  So at Sun, we have been
working around this by using AM_GLIB_GNU_GETTEXT which has a special test
for Solaris making things work.  It would probably be better if this could
also be fixed in AM_GNU_GETTEXT.

AM_GLIB_GNU_GETTEXT has the following special test-case to recognize
that allows it to work:

          AC_TRY_LINK(, [extern int _nl_msg_cat_cntr;
                         return _nl_msg_cat_cntr],
            [CATOBJEXT=.gmo
             DATADIRNAME=share],
            [case $host in
            *-*-solaris*)
            dnl On Solaris, if bind_textdomain_codeset is in libc,
            dnl GNU format message catalog is always supported,
            dnl since both are added to the libc all together.
            dnl Hence, we'd like to go with DATADIRNAME=share and
            dnl and CATOBJEXT=.gmo in this case.
            AC_CHECK_FUNC(bind_textdomain_codeset,
              [CATOBJEXT=.gmo
               DATADIRNAME=share],
              [CATOBJEXT=.mo
               DATADIRNAME=lib])
            ;;
            *)
            CATOBJEXT=.mo
            DATADIRNAME=lib
            ;;
            esac])

Would it be possible to get similar logic included in the AM_GNU_GETTEXT
macro?  I'm hoping it will be obvious to those working on gettext how
to integrate this into the AM_GNU_GETTEXT macro, but I would be able to
dig into this further if that would help.  I'd also be happy to test any
changes to make sure they work.

Thanks.
