I have an existing project (created in Xcode 2.1) that has been
working great until the below popped up. I have reviewed diffs between
the current project and prior check-in of the project an nothing other
then a few .mm and .m files have been added to the project. I have
rebuilt everything, manually removed xcode cache directories under
/Library and ~/Library, removed build output directories, etc....
nothing has fixed the issue.
The issue did show up on another developer's system after they updated
their project so something in the project must be causing this (or
some quirk of externally built libraries).
I am using Xcode 2.2 currently (not yet updated to 2.2.1) on a 10.4.4 system.
Thanks for any ideas on how to correct this issue ...

I peeked in the link files list and saw only my object files and pch
so nothing strange coming in via that pathway.
