Hi, While running your changed tests on Windows, I think I found new failures. Being a bot and all I'm not very good at pattern recognition, so I might be wrong, but could you please double-check?

In general, patches to wine should have some demonstrated benefit, either by increasing the number of passing conformance tests, or by making some app work better, or both. Your current patch doesn't seem to do either of these things. Getting into a pissing match with AJ about patent and copyright law is not a good strategy for potential contributors to wine. He generally knows his stuff, and I think he's right in this case. If I were you, I'd go off and reflect for a while, then pick some other way to contribute.

There was only a couple places where the argument was an expression and in those cases I did not see that the change would cause problems. Frankly, I do not think I could come up with a test where the change would make a difference. I am submitting the patch against the weird possibility that such a case does exist. The change is strictly preventative maintenance with just a hint of aesthetic improvement to make them coordinate with the 'Handle' variants of these macros. Now, if you are going to tell me that these definitions were *copied* from a Microsoft *source* rather than derived from a Microsoft specification, you would have a point, but then there would be a whole bunch of copyright issues that would need to be worked through.

This code is win32 only. > 'i', 'ui', 'l' and 'ul' are parameters to the macros, When the macros are used, you put in an expression as the argument to the macro. As originally written for example, the cast to LONG in ((LONG)l) is applied to only the first component of the expression substituted in place of 'l'. In order to get the cast to apply to the whole expression, you need parenthesis around the parameter. That is literally (l). Then the cast applies to the whole expression. That is (LONG_PTR)(l) casts the entire expression substituted into 'l' to a LONG_PTR value. The macros that convert to 'Handle' rather than 'Ptr' do this properly. In the vast majority of cases the expression substituted into 'l' is a simple variable and there is no problem. In almost all of the remaining cases, casting the first element of the expression coerces the rest of the expression to the proper type. In rare cases, other elements of the expression might force the expression's value to some other type. In most of those cases the cast to LONG_PTR fixes the problem. In a really odd case there might be a problem caused by the extra cast to LONG. Since that cast is buried in a macro definition, it will be difficult to spot that cast as the source of such a problem from the source code. The original definitions include three casts in sequence. The first of those casts is done improperly. Even if it were done properly, the next cast in the sequence makes it redundant. I removed the improper cast since it IS redundant. NUFF SAID?

This is caused by previously committed patches while testbot was resting, I'll fix these failures after today series gets in if it's okay.
