Excuse me if I'm posting this to the wrong place -- I am new to the caml
community.

Here is the bug description. Let's consider the following example:

--- test.idl ---
[
    object
]
interface IX: IUnknown
{
    HRESULT something();
}

[
    object,
    pointer_default(ref)
]
interface IY: IUnknown
{
    HRESULT_bool getBool();
    HRESULT_bool getIX( [out] IX **p );
}
--- end of test.idl ---

$ camlidl -header test.idl
test.idl

$ ocamlc -ccopt /Zi -c -ccopt test.c

test.c
test.h(43) : error C2061: syntax error : identifier 'HRESULT_bool'
...

$ ocamlc -ccopt /Zi -c -ccopt /DHRESULT_bool=HRESULT test.c

test.c
test.c(76) : warning C4047: 'function' : 'long ' differs in levels of indirection from 'long *'
test.c(76) : warning C4024: 'camlidl_c2ml_Com_HRESULT_bool' : different types for formal and actual parameter 1
test.c(76) : warning C4020: 'camlidl_c2ml_Com_HRESULT_bool' : too many actual parameters
test.c(100) : warning C4047: 'function' : 'long ' differs in levels of indirection from 'long *'
test.c(100) : warning C4024: 'camlidl_c2ml_Com_HRESULT_bool' : different types for formal and actual parameter 1
test.c(100) : warning C4020: 'camlidl_c2ml_Com_HRESULT_bool' : too many actual parameters
test.c(126) : warning C4020: 'camlidl_ml2c_Com_HRESULT_bool' : too many actual parameters
test.c(147) : warning C4020: 'camlidl_ml2c_Com_HRESULT_bool' : too many actual parameters

So the following bugs are obvious:

1. HRESULT_bool (and HRESULT_int) definition is missed in camlidlruntime.h
(or camlidl compiler should always generate code with HRESULT instead of them)

2. The way compiler uses camlidl_c2ml_Com_HRESULT_bool() and
camlidl_ml2c_Com_HRESULT_bool() does not conform to their
definition. Specifically, the generated code implies some context structure
parameter while camlidl_*_Com_HRESULT_bool() definitions have no idea about
it.

Of course, I can easily fix the first problem myself, but in the later case
I have to give up -- ocaml internals are still beyond my comprehension.

If someone is capable to fix that, I'd be very obliged -- it's currently
the real showstopper for me :-(

Hope to hear from you soon,
Dmitry
