Warnings are tricky. I fully agree that they should be cleaned up. But some times that is hard to achieve without introducing code that is obscure or fragile. That is not true in this case! There is a clear clean appropriate and informative fix. Applying it should be a no brainer.

People are tricker than warnings. At least warnings don't vacilate as their mood changes. It may be that the only way to get your (very desirable) patch applied is to eat copious quantities of humble pie, appologise profusely, and send a link to this thread.

If "typemap" is a header I would consider it essential that it "compiles clean". One of the worst things about warnings of this nature is that they hide other more important warnings by drowning them out, and that can waste a huge amount of time.

Good luck with following this issue up!
