Can you provide some test code (s. t/pmc/nci.t and src/nci_test.c) for
signatures similar to the real:
extern DECLSPEC void SDLCALL SDL_UpdateRects

No problem. Fair warning, though: nci_test doesn't build by default on
Linux PPC. I had to build it manually then copy it into
runtime/parrot/dynext/.
After commenting out the skipall() which doesn't like my platform, tests
5 and 27-29 fail. More importantly, the other tests pass.
After adding a signature for vpP to src/nci_call.txt and rebuilding,
only test 5 fails. That might be due to differences in the size of
shorts on this platform as compared to i386; just a guess. (The return
value is 128, while the test expects -128).
Anyhow, I've attached a new test which shows of more or less my idea for
what this should do. It may be horribly wrong, but it's wrong in a way
that has actual code, not just vague ideas.
On the other hand, I'm really *not* a C programmer.
