[omniORB] omniORB_280 and Sun C++ 5.0

[Brian Tolley]

I had similar error messages when using the Sun C++ 5.0 in version 4.0
compatibility mode with C++ namespace support enabled.

In my case it was apparently caused because the compiler objected to there
being two routines with different signatures in the same C++ namespace.
When I forced omniORB to declare 'omniORB' as a C++ class rather than having
it as a 
C++ namespace (by editing the 'CORBA_sysdep.h' so that
'HAS_Cplusplus_Namespace'
is not defined) the problem went away. I assumed this was a compiler fault,
but perhaps someone with more C++ knowledge than me will say whether or
nor C++ allows overloaded functions in the same C++ namespace. 

However I do not know however why you are getting the fault with the Sun C++
5.0 compiler (not in V4.0 compatibility mode), perhaps there are still C++
namespace
bugs in the compiler.
