Checked it on both i686 and x86_64 environments as follows:

$ sh -xc 'uname -srvmpio; cygcheck -c asymptote libOSMesa8; cygcheck asy; strace asy' > asy-`uname -m`.log 2>&1

The logs are attached to this mail.


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'
