[omniORB] linking error (duplicated-simbol) only with option(-g)

[Luke Deller]

It looks like your compiler in its compatibility mode is having problems
with static class members which are initialised in the header file.
Microsoft's C++ compiler also has problems with this.

There is a workaround which causes these static class members to be
initialised in the c++ file rather than the header file for Microsoft's
compiler.  You might want to try enabling this workaround for yourself
too.  Look for the definition of the macros _init_in_cldef_ and
_init_in_cldecl_ in omniORB4/CORBA_sysdep.h

Regards,
Luke.
