Hej Marco---
Thanks for your reply. I tried to send the cygcheck output to the
Cygwin mailing list last week, but the file was too big (2M) and the
post was rejected. I therefore put the file on a temporary platform
for file exchange:
http://exporter.nsc.liu.se/2ce844aaa0014c9f9cf889f2b062fdc7/cygcheck.out
from where you should be able to fetch it.
I tried to repeat exactly the example that you suggested, no success
unfortunately. I attach the XWin logfile, maybe it helps you to spot
anything.

Hi Klaus,
my guess is that there is an issue with the drivers
[183955.593] (EE) AIGLX: No native OpenGL in modes with a root window
[183955.843] (EE) AIGLX error: dlopen of /usr/lib/dri/swrast_dri.so
failed (No such process)
[183955.843] (EE) AIGLX error: unable to load driver swrast
[183955.843] (EE) GLX: could not load software renderer
[183955.843] (II) GLX: no usable GL providers found for screen 0
Aha, I suspect the problem here is the same as [1].
You have no OpenGL, because the software rasterizer requires LLVM, and
is failing to load due to that bug.
Please try updating to the latest Cygwin.
