Sadly, setup-x86*.exe is a native Windows process, not a cygwin process
(and MUST be, since you can run setup prior to having cygwin installed).
 So it is unfortunately stuck at the Windows limitations on max
command-line+environment sizing.

Of course, patches are welcome, if someone would like to propose a way
to make setup-x86.exe read its package list from a file name given on
the command line, rather than having to pass every package name on the
command line.
