This is mentioned as a known bug in the ranlib man page.  We work around
it by copying the .a files and running ranlib on the copies; but we have
a Makefile-based build system, so it is very easy to do there.  In
Xcode, you probably have to add a shell script build phase that does
this; if you set the input and output files of the build phase
correctly, it should only kick in when a new version has come in from
CVS.

They are text files, so just diff them to see what has changed.  I have
seen cases where a build product's entry changed from lastKnownFileType
to explicitFileType after building, or something like that.
