--- bogus defns for win32
+-- 'raw' mode for Win32 means turn off 'line input' (=> buffering and
+-- character translation for the console.) The Win32 API for doing
+-- this is GetConsoleMode(), which also requires echoing to be disabled
+-- when turning off 'line input' processing. Notice that turning off
+-- 'line input' implies enter/return is reported as '\r' (and it won't
+-- report that character until another character is input..odd.) This
+-- latter feature doesn't sit too well with IO actions like IO.hGetLine..
