[omniORB] DynAny trouble building latest snapshot

[bjorn rohde jensen]

Hi,

 I have just build the latest few hours old snapshot on my mandrake 8.0
box
using gcc 2.95.3, which, much to my suprise, required hacking around a
bit
in the DynAny code to resolve a few ambiguities....

The very lovely inheritance graphs, if that is the word for it, which
gcc finds
ambiguous look something like this:

_NP_decrRefCount()                              CORBA_OBJECT
                                                     |
                                                  DynAny
                                                /        \
_NP_decrRefCount()                      DynAnyImplBase    \
                                              |          DynFixed
                                         DynAnyImpl        /
                                               \          /
                                                DynFixedImpl


 I am rather puzzled by g++'s error message, the overloading does not
look
ambiguous to me, so to shut up g++ i qualified the call selecting
DynAnyImplBase::_NP_decrRefCount()
I suppose, i will find out, if that is right or wrong...

Yours sincerely,
