In the November 2002 release of Hugs for Mac OS X, Control-D apparently no longer signals end of keyboard input. Is there some other signal that causes hugsHIsEOF to return True?

Same on Linux (and not just with this release, I think). This is just part of Hugs's strange treatment of stdin: it turns off canonical processing (including the special meaning of ^D) and echoing. Then getChar echoes characters on stdout (which is not always right) but getContents and hGetChar stdin don't.
