So we can remove the second invocation of mpc after build is complete?

Hmmm... Directly under /usr/share/idl? I'd go for /usr/share/idl/TAO
(we do something like that for omniORB)

What I had in mind was simpler and relied on macro magic only. I don't
think get_dll_names has to be changed if we can propagate the version
of the dll to load to it.

Let's take an example: in
$TAO_ROOT/orbsvcs/orbsvcs/PortableGroup/PortableGroup_ORBInitializer.cpp, we 
see:
> static const ACE_TCHAR pg_poa_factory_directive[] =
> ACE_DYNAMIC_SERVICE_DIRECTIVE("TAO_GOA",
>                               "TAO_PortableGroup",
>                               "_make_TAO_PG_Object_Adapter_Factory",
>                               "");

I imagine either something like that:
> TAO_DYNAMIC_SERVICE_DIRECTIVE("TAO_GOA",
>                               "TAO_PortableGroup",
>                               "_make_TAO_PG_Object_Adapter_Factory",
>                               "");
with TAO_DYNAMIC_SERVICE_DIRECTIVE a conditional #defined macro that
knows TAO version and appends it to its second argument so that it
becomes for instance "TAO_PortableGroup" "-1.7.7" and it will work;

or like that:
> ACE_DYNAMIC_SERVICE_DIRECTIVE("TAO_GOA",
>                               TAO_VERSION("TAO_PortableGroup"),
>                               "_make_TAO_PG_Object_Adapter_Factory",
>                               "");
TAO_VERSION being very akin to what I described above.

So far I think the latter is simpler, but I have not tried implementing
any of these.

Do you think it's doable?

Thomas
