           Summary: Driver binaries cross-compiled with MinGW (PE) have

           Product: Wine
           Version: 6.11
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P2

Hello folks,

while investigating bug 51375 ("SCM erroneously tries to start 64-bit kernel
drivers as 32-bit service due to incorrect handling of 'IMAGE_FILE_DLL' image
characteristics in 'kernel32.dll.GetBinaryTypeW' (Protect DiSC
'acedrv11.sys'))", I've found another discrepancy:

$ pwd

acedrv11.sys: PE32+ executable (native) x86-64, for MS Windows

All driver binaries which have been cross-compiled with MinGW (PE) have
'IMAGE_FILE_DLL' image characteristics set which is rather unusual.

Real native and Wine builtin 'fake' drivers are fine.

This doesn't cause a problem in shared WoW64 prefixes under Linux but still
could be addressed.

$ wine --version
