* include/sys/cygwin.h (PID_NOTCYGWIN): New enum.

Browse Source 
* spawn.cc (spawn_guts): Set a flag when a process is not a cygwin process.
* fhandler_tty.cc (fhandler_tty_slave::init): Remove previous change.  Try a
different method to determine when we should become the process group owner.
* signal.cc (kill0): Remove archaic code which dealt with never-set flag.
