Is there any way that gcc and/or XCode could tell me what include files my project is actually using?

What I'd like to do is remove any header files from the project that are not actually in-use by my code.

gcc's -M flag will run the preprocessor (only) and emit makefile fragments for the current source file's dependencies. This can't easily be made useful from Xcode (though I guess a separate target with a special .c/.cpp/.m rule might take care of it), and you'll have to massage the results, but it's a start.
