CORBA35 — COM/CORBA keywords

Summary: I can"t find in the COM/CORBA spec parts A and B any mention of how to
deal with IDL identifiers that are keywords to the Microsoft "mktyplib" tool.
This tool mangles the following identifier (not necessarily a complete list) by
prepending them with "_":

"BSTR", "CALLCONV", "coclass", "CY",
"CURRENCY", "DATE", "DECIMAL", "DISPID", "DISPPARAMS",
"dual", "EXCEPINFO", "guid", "GUID",
"HRESULT", "importlib", "IDispatch",
"INTERFACEDATA", "IUnknown", "LCID",
"METHODDATA", "odl", "oleautomation",
"PARAMDATA", "properties", "propget", "propput", "retval",
"SAFEARRAY", "SAFEARRAYBOUND", "SCODE",
"VARIANT", "VARIANTARG", "VARIANT_BOOL",
"VARTYPE", "VARENUM"

As far as I can tell, the output of the "mktyplib" tool makes use
(directly or indirectly) of the regular C++ bindings, whose identifiers
are not mangled the same way. This makes it impossible to emit COM bindings
for IDL files that contain the above keywords.

The problem that I"m running into is in CosTrading IDL, where the identifier
"properties" is used.
