| | | | | | | | | | | | | | | | | | | | | | * include/sys/cygwin.h: Remove PID_ZOMBIE. * pinfo.h: Rename EXITCODE_* defines. (pinfo::set_exit_state): Remove parameter. * pinfo.cc (set_exit_state): Remove parameter. Reverse sense of test so that exitcode is checked for having been set rather than not having been set.

Set flag when exitcode has been established. Reflect change in arguments to set_process_state. (proc_waiter): Reflect change in arguments to set_process_state.
