Interesting stuff. You provided a good place to start. Obtaining the latest gcc, building, and breaking gets me in the ballpark at 'duplicate_decls' in 'cp/decl.c', although more work is required to understand what happens to the function declaration data after the merge. Your advice about submitting a patch request is a nice option. I'm still figuring out what to do. Thank you for your help. Jerry.
