          Issue ID: 24782
           Summary: mmsystem header has align(1): near top
           Product: D
           Version: D2
          Hardware: All
                OS: Windows
            Status: NEW
          Severity: minor
          Priority: P1
         Component: druntime
          Assignee: nobody@puremagic.com
          Reporter: destructionator@gmail.com

ttps://github.com/dlang/dmd/blob/master/druntime/src/core/sys/windows/mmsystem.d#L21

in upstream still too. another bug caught by safer by default?

that looks just plain wrong, but also not super important since things are pointers and dwords

contrast to this thing generated from the microsoft xml: https://github.com/rumbu13/windows-d/blob/master/out/windows/multimedia.d#L576

this has align(1): inside the struct, which is different than outside the
struct!

either one is wrong and the other is right, or they're both wrong

this mingw based thing from wine also doesn't have an align setting.

https://github.com/wine-mirror/wine/blob/master/include/mmsystem.h


feels wrong to me, want second opinion.

this potential bug caughed by OpenD Safer By Default btw: arsd\simpleaudio.d(2274): Deprecation: field `WAVEHDR.lpData` cannot modify misaligned pointers in non-`@system`/`@trusted` code
