problems with sync_type 'replication support only'

Hi,
I try to setup a transactional push replication from MS SQL Server 2005 to Sybase ASE 12.5.3. ASE is known to MS SQL Server as a linked server using OleDB.
As table schema and data are valid at subscriber site I don't need a initial snapshot for the replication.
So I do some tests with sync_type (sp_addsubscription). First I tried 'none'. That works fine.
But the documentation says that it is depricated an I should use 'replication support only'.
But with this syn_type replication stops because is sends the following commands to the subscriber:

--
-- Transactional replication custom procedures for publication 'kunktable_pub' from database 'kunktest2':
--
----
---- Replication custom procedures will not be scripted for article 'kunktable' because the auto-generate custom procedures schema option is not enabled.
----

 IF (@@microsoftversion >= 0x09000000) BEGIN EXEC sys.sp_MSrepl_setNFR @schema = N'dbo', @object_name = N'kunktable' END

Of cause Sybase ASE throws an error 137 'Must declare variable '@@microsoftversion' because it has no system variable @@microsoftversion. Furthermore a procedure sys.sp_MSrepl_setNFR is not known at ASE site.

So it seems, that sync_type ''replication support only' only works for MS subscriber but not for ODBC or OLEDB based subscriber like SYBASE.

Question:
Do I miss something ?
Is this a bug ?
Which sync_type should I use ?
