[xsd-users] gcc warning

[Rizzuto, Raymond]

Boris,

I'm glad to hear that the warning isn't caused by anything I am doing wrong.

Unfortunately, I can't move to a new version of gcc till I move to sles 10, which I can't do yet because of other dependencies.

I am using the (int &) work-around for now.  That works, so I'll use that for now.

Thanks again for all the help.

Ray

This is a well-known, bogus warning in older versions of g++.
Unfortunately I don't have access to the version that produces
this warning so I couldn't test my work-arounds (g++ 3.3.6 as
well as 3.2.3 that I have access to don't have this bug).

I think the following should work (besides upgrading the compiler,
of course):

functionTakingAnInt((int&)stock.get_id ());

const ReferenceDataId& id (stock.get_id ());
functionTakingAnInt(id);

Making stock const should also help. If you don't plan to modify
stock then this might be the cleanest approach.
