-	isatty for mingw -	libthread: works mostly, daemonizing works not -	libdraw:	works basically, tested with tcolors, acme		and sam. Events have not been ported, so only		programs using the thread-based mouse		interface will run. -	cmd/test.c might need an update -	cmd/ed.c could be made linkable again -	cmd/9term/win.c could be ported, so that	acme would also have a shell on Windows/MinGW
