        * configure.in, scripts/cxx.m4, glibmm/glibmmconfig.h.in: Added new
        compiler tests.
        1. To see whether it allows use of non extern C functions
        as extern C callbacks, because the Tru64 compiler does not
        allow this, when using strict_ansi. We do not actually use this yet.
        2. To see whether it allows us to define a template that uses an
        undefined type, even if we do not use it before defining the type.
        Tru64 does not allow this. That's probably correct.
        * glib/glibmm/container.h: #ifdef out a dynamic_cast that Tru64
        does not allow, and which I can not think of a better place to put.
        See the comment in the code.
        * glib/glibmm/containerhandler_helpers.h: When the compiler does not
        alllow the GObject and GtkObject (dynamic_cast of) specializations
        here, then put them in glib/glibmm/object.h and
        gtkmm/gtk/src/object.hg instead.- needed by Tru64 compiler.
        * glib/glibmm/value.h, value_custom.[h|cc]: Conditionally moved
        the RefPtr Value specialization into object.h, as above.
        * glib/src/ optiongroup.ccg, spawn.ccg, thread.ccg: Make C callacks
        separate extern C.
        * glib/src/optiongroup.ccg: Do not use the StringArrayHandle,
        because the Tru64 compiler has problems with it - see comments
        in code.
        * glib/src/optionentry.hg: Remove the include of value.h, because
        it is not used and it causes a Tru64 compile error in
        optioncontext.cc because its templates are included before the
        types that the template uses.

        * configure.in, scripts/cxx.m4, glibmm/glibmmconfig.h.in: Added a
        compiler test, because the IRIX MipsPro compiler does not allow the
        inline initialization of ustring::npos.
        * glib/glibmm/ustring.[h|cc]: When the compiler does not support the
        inline initialization of npos, initialize it in the .cc file.
        Declare partial specializations of the SequenceString inner class
        inside the class - needed by IRIX MipsPro compiler.
