I do not see GPCtypes.pas in my GPC installation.

Sure.  GPC has very simple mapping between C and Pascal types.  But
the catch is that both in C and in Pascal you may define your own
types.  Translating type definitions between  C and Pascal is not
hard.  However, since neither C compiler can can read Pascal nor Pascal
compiler can read C one has to do translation by hand (or use
some extra tool, but I can not recommend any).

GPC distribution contains an example (gpc_c_c.c + corresponding
Pascal files) of linking Pascal routines to C.
