Created an attachment (id=27369)
 --> (http://bugs.winehq.org/attachment.cgi?id=27369)
patch: For MCI parsing, use 64bit compatible structures.

Here's the current version of the first patch. It could be simplified a little
by what I put in git meanwhile.

It's the first of three patches that should allow MCI to work on Wine64.
2. Fix offset calculation in MCI_CONSTANT (not yet written).
3. Introduce MCI_HWND etc. and other such DWORD_PTR sized objects (done).
(not mentioning tests).

The advantage of that approach is that a 4th one could be added anytime after
we learn whether or not MS introduced new constants for 64bit objects in 64bit
MCI drivers: there would be few things to change.
