Oh, it's to drop the const.
Yeah, it doesn't matter in that case. (Casting to drop a const usually
means mis-structured code, but unwinding innfeed to try to do something
different is probably more trouble than it's worth for STABLE.)

Please send questions to the list rather than mailing me directly.
<http://www.eyrie.org/~eagle/faqs/questions.html> explains why.
