Hi Jeff, sure like to try to explain the matters. The script check_unnecessary_headers.sh is not smart at all. It checks whether a header, if known, is required due to some content. It does not know about hierarchies of include files, or convenience headers such as bindings.h and would delete the very headers mention below from bindings.h.
Now, only if we switch to a more sophisticated method (ctags?, munching gcc's preprocessed output?), this could be handled. My personal opinion however is, that every header and every source file should be self contained: It should include all the headers with symbols it needs, no less, and certainly not more ;-) Hope, this is a satisfactory answer?
