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?
