            Bug ID: 51919
           Summary: New sal.h macros break libstdc++ includes in wineg++
           Product: Wine
           Version: 6.20
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winelib
          Assignee: wine-bugs at winehq.org
          Reporter: mail at robbertvanderhelm.nl
      Distribution: ---

https://github.com/wine-mirror/wine/commit/dfdf56fbe47f8ff50ebe533e6d73f2de6546f008
added a bunch of new (empty) macros. These macros include definitions for __in
and __out. These names are used often for function arguments in libstdc++,
whose
headers now no longer compile under Wine 6.20's wineg++ after including
windows.h. A minimal example of the problem is this:

    #include <windows.h>
    #include <algorithm>

    int main(int argc, char *argv[]) { return 0; }

Compiling the above with `wineg++ --std=c++20 <filename>.cpp` with GCC 11.1 now
results in 977 lines of compiler errors.
