Thank you, Marco!
On each systems, there appeared a dialog telling something like that:

   The procedure entry point 'glBegin' could not be located in the
   dynamic link library 'cygOSMesa-8.dll'


I would say that libOSMesa8 had a modification in the list of
exported symbols in the last version.

[TXT]    libOSMesa8-17.3.5-1    21-Feb-2018 09:50     267
[TXT]    libOSMesa8-17.3.8-1    05-Apr-2018 12:44     267
[TXT]    libOSMesa8-18.0.1-1    23-Apr-2018 07:35     267

I do not see  glBegin in the last cygOSMesa-8.dll of 18.0.1-1
So it seems there is an issue on the last libOSMesa8 package

Thanks for tracking this down, Marco. So the workaround is to downgrade to the previous version of libOSMesa8.

I noticed that for the latest mesa, Yaakov switched from an autotools build to a meson build. I wonder if the problem with cygOSMesa-8.dll is an unintended side effect of that switch. I tried building mesa-18.0.1 using autotools instead of meson (taking the configure arguments from the cygport file used for mesa-17.3.8), and the resulting cygOSMesa-8.dll does export glBegin.
