* prevent duplicate symbol errors when compiling code with debug info

Browse Source 
on AIX due to the extra inserted local symbols (although in case e.g
   multiple procedures contain a typed constant with the same name, only
   one can be accessible)
  * removed '.' suffix of local symbols inserted for debug info of typed
    constants for AIX (gdb couldn't find those symbols; it seems the
    address calculated by gdb for typed constants is still not correct
    though)
