[GT] scan.pl on cygwin

["Weigert, Thomas" <weigert AT mst.edu>]

scan.pl uses IPC::SysV to communicate results between forked processes.

On cygwin, this does not seem to work, at least not on my installation;
calls to the IPC library fail. Does anybody have any suggestions on how
we could collect up the results of individually forked processes (other
than storing it into a file) without using IPC::SysV? Or suggestions on
what could be wrong with the library/code?

Thanks, Th.
