Screenshot of problem (QEMU virtual session and Wine, side by side)

When an 16-bit Windows application displays a listbox and manually fills it
with DlgDirList (not as a part of a Common Dialog), the flag combination
DDL_DRIVES|DLL_DIRECTORY should make files appear according to the set filter.
Wine does not do this, as it (incorrectly) appends DDL_EXCLUSIVE to the bitmask
of flags before delegating to 32-bit code.
