mingw-w64 project imports some of our headers, including most of d3d headers. They would probably prefer to keep them with 'l' modifier since that's the right thing to do. Given that it's mostly harmless for Wine, could we please consider not changing it?
Thanks, Jacek

Well ... the the dinput.h was a real change were Wine was affected. But the change should be mostly harmless for mingw-w64 as long == int on Win32 and Win64.
Anyway this is a hit job from Alexandre so you'll have to convince him.

As Jacek mentioned already, it would be for our use of Wine direct-x SDK a big flaw to have constants here not proper suffixed with L. Especially in use for C++ this would cause big pain for 32-bit and 64-bit native Windows compilation. I am not sure about this, but I assume that Wine might have an interest to be able to use platform-headers and optional SDKs also with a cross-compiler targeting for Windows native.
I would suggest to use here a helper-macro, which does on demand the required L-suffix. Something like in global configure headers: #ifdef __SIZEOF_LONG <= 32 #define MSABI_LONG(VAL) VAL ## L #else #define MSABI_LONG(VAL) VAL #endif
And then using in platform/sdk headers
... #define XYZ MSABI_LONG(0x1234) ...
instead.
Regards, Kai

Well ... the the dinput.h was a real change were Wine was affected. But the change should be mostly harmless for mingw-w64 as long == int on Win32 and Win64.
The compiler does still complain about types even if the type is the same size. Such as when using printf formatting (%x = int, #lx = long; GCC complains if the type doesn't match, even if it's the same size). Also I could imagine some C++ function overrides tripping up with the int/long difference.

Right, one of the reasons we do this change for Wine.

If you use the Wine headers this should actually fix it as it brings the numeric constants in line with the types as LONG == int in Wine.

For Wine it doesn't really matter, since we can't use C++. For mingw-w64, however, it could be a big problem if it's not properly typed as a long. Overloads and template types would silently use 'int' where it should be using 'long', and you wouldn't necessarily know until you see odd behavior in the app.

What kind of odd behaviour? Both int and long are 32-bit in win32 and win64.

-- Dmitry.
See as example for C++:
#include <stdio.h>
void foo (int i) { printf ("int i == %d\n", i); } void foo (long i) { printf ("long i == %ld\n", i); }
int main () { foo (1); foo (1L); return 0; }
if you compile this program and execute it, then you will see the following output:
$ ./tst.exe int i == 1 long i == 1
C++ has the ability to have for same function name different implementation for different argument types. Means, argument types getting part of function's signature. So you might see the cause what is different about suffixed/non-suffixed values for C++.
