* external.cc (cygwin_internal): Implement CW_CMDLINE.
* pinfo.h (SIGCOMMUNE): New signal type. (commune_result): New structure for commune functions. (picom): New enum for commune functions. (_pinfo::hello_pid): New. Pid who's communicating with me. (_pinfo::tothem): New. Handle of communicating pipe. (_pinfo::fromthem): Ditto. (_pinfo::commune_recv): Declare. (_pinfo::commune_send): Declare. (_pinfo::alive): Declare. (_pinfo::cmdline): Declare. (_pinfo::lock): Declare. * pinfo.cc (set_myself): Initialize new _pinfo lock. (_pinfo::alive): Define. Determines if process still exists. (_pinfo::commune_recv): Define.
