[omniORB] compiling omniORB3 on NT

[Ji-Yong D. Chung]

    Continuing the compiling of omniORB3 on NT ...

    I was looking at the files, and it seems that undefining _core_attr m=
ay
cause problems.

    The files which should export the variables are in (I think) orbcore.
Since dynamic
is importing variables, it must declare dllimport (which gets erased by
undefining
_core_attr).  Similarly for all other libraries that are importing from
orbcore.

    The reason the errors are appearing, as I am guessing, is that, in th=
e
dynamic,
_core_attr (which is tranlsated to dllimpot) is being used together with =
a
definition.  The
CORBA.h seems to try to initialize a variable.

    For example, if you look at the line that was the cause of the first
error message:

 _CORBA_MODULE_VARINT _core_attr const ULong
       OMGVMCID _init_in_decl_(  =3D 1330446336 );

_init_in_decl is apparently trying to initialize a variable, and this is =
not
allowed to be used
with _core_attr.
