Thanks. I have a followup question. Currently, reading input with timeout basically doesn't work on MS-Windows, and the ability to find out how many characters are available for input is severely limited (the calling application can only know if one or more input characters are available, but not how many, and the timeout specification to wait for input to become available is ignored). My question is how important is it to support this on MS-Windows? The Posix implementation uses pselect and ioctl/fcntl and similar APIs, which won't work on MS-Windows, but there are ways of implementing the same functionality on Windows using alternative Windows-specific APIs. If these features are important to have, and their importance justifies making the sources use more #ifdef's and be slightly harder to read, I can work on adding them. Do you know if there are any applications which use Readline and can be built on Windows that need this functionality?
