This reverts commit 323b62310a.
The previous commit breaks the Win32 setup generation on the buildbot
since it is not adapted to HTML documents for the README and for the
NEWS files yet. Sorry for the noise.
This fixes an OpenGL renderer issue for builds with MSYS2/Mingw64 or MSYS2/Mingw32
The issue pertains to MSYS2 adding a default manifest file (default-manifest.o) to the executable
The bug is for PC systems with GPU drivers that were not properly supported for Windows 10
systems, like Intel HD Graphics series 1st and 2nd generations. In those systems, launching a
game in ScummVM (built with MSYS2/Mingw) with the OpenGL renderer would cause the game
screen to be a white blank image, and various warnings would be output to the console, eg.
"WARNING: GL ERROR: GL_INVALID_ENUM on glTexSubImage2D(0x0DE1, 0, 0, area.top, src.w, area.height(), _glFormat, _glType, src.gere.cpp:167)!"
This was due to MSYS2/Mingw builds trying to load the (poorly supported) GPU driver while advertising support for Windows 10 in their
embedded default Manifest file. Hence, the GPU driver DLL (eg ig4icd64.dll) would be unloaded, causing the bug.
