Assume I terminate Cygserver and any other Cygwin services running, I then start "ash.exe" by double clicking it in a Windows Explorer window, from the command line in the "ash.exe" window I start my Ash Shell script which in turn starts "setup-x86*.exe" with a very long command line. Am I interpreting you correctly in assuming that under these circumstan- ces the maximum length of this command line is 2 * 10**9 ASCII charact- ers on my box? This would be just enough I think.
