I would keep it in the mail build. If I recall correctly, this code
is here to test the *ICD Loader* itself (with a specific *fake ICD*).
That explain why there is no need to stick to the real prototypes :
the first argument must be a pointer (required by the spec), other
arguments are not used by the ICD Loader.
Using fake (simpler) prototypes allow to generate automatic tests.
Of course, using run_dummy_icd_through_our_ICDL with a real ICD would
probably crash.
So, for now, my position is that I will keep this test in the
Debian package and I won't patch upstream software to tweak each
prototype manually (instead of using upstream automatic code
generation) in this test.
That said, if upstream find (or someone provides them) a way
to use the real prototypes, I will of course use them in the
Debian package. Or another possibility would be for you to tell
us how to desactivate this compiler check here (a pragma?)
