  Why is it a so common misconception that you should put all the data types
of a .c file into its correspondent .h file?
  A .c file is a module, and its correspondent .h file declares its
*public interface*, that is, it declares the part of the module which other
modules need to see.
  Internal data types (and functions) used by the module are *not* part of
this public interface. Also global variables used solely in this module (even
though we don't use global variables, do we?) should be declared as static in
the .c file, not in the .h file. The .h file should always be as minimal as
possible.

  As for your actual question, I didn't understand it well enough to write
a proper answer.
  (Perhaps a really short example could help?)
