	cygwin         : ChangeLog fhandler_fifo.cc pinfo.cc pinfo.h 
	                 sigproc.cc 
	cygwin/include/cygwin: signal.h 

Log message:
	Change name from commune_recv to commune_process throughout.  Change name from
	commune_send to commune_request throughout.
	* pinfo.h (PICOM_EXTRASTR): New flag.
	(PICOM_FIFO): Define with new flag.
	(_pinfo::hello_pid): Delete.
	(_pinfo::tothem): Delete.
	(_pinfo::fromthem): Delete.
	(_pinfo::commune_process): Rename from commune_recv.  Add a siginfo_t argument
	to declaration.
	(_pinfo::commune_request): Rename from commune_send.  Change DWORD to
	__uint32_t in declaration.
	* pinfo.cc (_pinfo::commune_process): Rename from commune_recv.  Add siginfo_t
	argument.  Use information from argument rather than reading from another pipe.
	Synchronize with other process's commune event.
	(_pinfo::commune_request): Rename from commune_send.  Change DWORD to __uint32
	in argument.  Fill out information in new siginfo_t element and rely on
	extended operation of sig_send rather than trying to deal with synchronization
	issues here.  Use process handle and read pipe information filled out by
	sig_send to gather information from the other process.
	* sigproc.cc (sig_send): Take special action if "communing" to ensure
	synchronization with the other process and to return information about the
	other process to the caller.
	(talktome): Accept a siginfo_t and handle arguments.  Read additional
	information from the signal pipe when _si_commune._si_code has the
	PICOM_EXTRASTR flag set.
	(wait_sig): Pass the transmitted siginfo_t struct and the pipe handle to
	talktome.  Close pipe read handle as soon as possible after we detect that
	we're exiting.
