Excuse me, but "entry" was not implemented in C, so it's not a matter
of "putting it back", nor is an unimplemented (and undefined!) feature
of the language by any means useful for what you suggest or for anything
else.  Anyway, your suggestion is already met by normal C function entries;
nothing (except complexity) is gained by multiple function entry points.

C++ provides much better "package" facilities than straight C and is
worth looking into.
