The long type on x64 Windows is 32 bit, on x64 Linux (and most other
platforms) it is 64 bit.
To deal with that difference, Wine defines LONG to be int (and ULONG
to be unsigned int etc), which is 32 bit on all the relevant platforms.

So yes, substituting PULONG for unsigned long * is wrong, it needs to
be ULONG *, DWORD *, or similar. The compiler warning that you get from
the correct prototype would be because you're also using a (lowercase)
long when calling the function -- this also needs to be an uppercase
LONG.

If this works in PSDK, then a fix for Wine's headers is probably
preferable -- but I have no idea how intrusive that would be, so a
workaround like this could be appropriate for the time being.

That sounds right ;)  (although a step-by-step approach should be
okay, so I don't think you have to implement this right away)
