However for the debugging output I disagree. I orginally thought as Francois (and you it seems) that handles are pointers and should be treated as such. But then I realized that when we implement Win32 on 64-bit platforms we can't have handles as pointers even internally if we wan't to support x86 emulation and even exposing a 64-bit handle to Winelib application can only cause trouble since they might store it is a 32-bit memory location. Sure we will probably be able to handle 64-bit pointers truncated to 32-bit by storing all objects in the lower 32-bit part of memory, but fear it might cause trouble all the same.
Handles are pointers in the Windows API, and they should be pointers inside of Wine. On a 64-bit platforms pointers will be 64-bit, and so will handles. If you want to run 32-bit code on such a platform you need a conversion for pointers anyway, so you might as well use the same conversion for handles. Not to mention that some handles are actually pointers (like HMODULE). So no, there is absolutely no reason to force handles to be 32 bits.
Beside doing TRACE("(%p)", handle) on 64-bit platforms will needlessly display the always the same presumably zero upper 32-bit part of the handle. That why I decided to should use TRACE("(0x%08lx)", (DWORD) handle) instead to avoid such issues.
Sorry but this is wrong. Handles are pointers and must be printed as pointers. Assuming that handles are always exactly 32-bit is very shortsighted.
The real reason that we should support compiling Wine with -DSTRICT is not because handles becomes pointers but because callbacks gets the correct prototype.
No, it's because handles become pointers; you cannot do the -DSTRICT typechecking with integers anyway. Callbacks are a very minor issue; the real point is to fix all incorrect handle manipulations, like implicit 16-bit handle conversions or arithmetic on handle values.
