Bug ID: 50378
           Summary: dlls/amstream/tests/amstream.o error: unknown field
                    ‘dwBitMasks’ specified in initializer
           Product: Wine
           Version: 6.0-rc2
          Hardware: x86-64
                OS: Linux

in distro:

# uname --kernel-release

# gcc --version

# ldd --version
2.10.1

Compiling wine-6.0-rc2 fails with multiple items:
error: unknown field ‘dwBitMasks’ specified in initializer
warning: large integer implicitly truncated to unsigned type
error: unknown field ‘dwRGBBitCount’ specified in initializer
warning: integer constant is too large for ‘long’ type

config line:
configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
--x-includes=/usr/X11R7/include --x-libraries=/usr/X11R7/lib --with-x
--libdir=/usr/lib32 CFLAGS="-O2 -march=i686 -mtune=i686"

I imagine other bug [1] is still present, but this new bug stops compilation
first.
