The difference seems to be that subsystem >= 6.0 return 4 from
GetSystemMetrics(SM_CXSIZEFRAME) while 5.2 returns 8, or something like that. I don't know if it's worth replicating, but with this MR we should be able to select a specific version for some test executable. If this is the difference, then I'd argue we should probably fix the tests to not depend on that, especially something higher level like dxgi or quartz. What do the failures look like?
That would be much more work, and it can be done later fairly easily by removing the EXTRADLLFLAGS.
This MR aims at making the compilation consistent between MinGW and Clang and this will make testing easier as it won't depend on the compiler defaults anymore.
See https://test.winehq.org/data/d62035da4aa91327c6e38a2c8a66b829eb0983ed/win22H... for the dxgi failures.
