I don't think hSetBinaryMode can be implemented on top of stdio (which Hugs uses): openBinaryFile fopens a file with mode "rb" etc to turn off CRLF processing on systems that have that feature, and there's no way to change it later.

And I'm not sure if hPutBufNonBlocking and hGetBufNonBlocking can be implemented on top of stdio. I've implemented the java.io package for my previous company, and we had to switch to file descriptors to get the required (non-)blocking behaviour. Perhaps we have to abandon stdio in Hugs at some point, too... Cheers, S.
