This is strange. On my Windows msys2 system, I didn't even notice the 
OpenGL code was silently enabled. The code compiles without issues. 
Today I enabled the GtkGLArea code initialization in ui/gtk.c to test 
OpenGL acceleration on Windows.

Well, it's a start. On a Linux guest system the WebGL Aquarium frame 
rate increased from 6fps to 14fps while the host processor load went 
down from 100% to 65%.

QEMU was started with:
./qemu-system-x86_64.exe -accel whpx \
-machine pc,usb=off,vmport=off,kernel-irqchip=off \
-cpu Skylake-Client-v4,tsc-deadline=off,x2apic=off \
-smp 4,sockets=1,cores=4,threads=1 \
-device virtio-vga-gl,xres=1280,yres=768,bus=pci.0 \
-display gtk,zoom-to-fit=off,gl=on \
-trace "gd_gl_area_*_context" \
...

This is the start of the QEMU log file:
Windows Hypervisor Platform accelerator is operational
qemu: GtkGLArea console lacks DMABUF support.
