Well, my question still stands: why aren't the other four flex outputs
also broken? They all use ECHO.

In any case, I'd prefer to see this fixed by not including <termios.h>
rather than hacking up the .l files. Surely it doesn't need to be
included everywhere, as src/include/port/qnx4.h is now causing to
happen. In fact, it looks to me like qnx4.h probably includes and
defines a lot more than it needs to; would you experiment with stripping
it down?

That strikes me as *horribly* dangerous. There is too much code whose
behavior might change in unpleasant ways if Size becomes a signed type.
Please explain what problems you are seeing that make you think this is
a good idea.

Andreas, the QNX port is largely your work IIRC. What do you think of
these issues? Have you tried 7.1beta on QNX?
