Sven,
 
    It gets better.  Since the "termio" structure is set to zeroes
immediately beforehand, it looks like the entire "cfmakeraw" call is
ineffective.  The "cflag" and "iflag" fields are reset immediately after the
call and the "oflag" and "lflag" fields are modified with "&="--and "&" to a
zero field has no effect.  So I suggest we just cut the whole thing out
entirely.

Sven, 

        In looking at the code in "freeglut_input_devices.c" starting around
line 260, I note that we now first modify the fields in "termio" and then we
set them.  Since we've replaced the call to "cfmakeraw" with a set of bit
assignments, perhaps we could combine these bit assignments with those that
come immediately afterwards.  It would make the code marginally simpler and
marginally more efficient.
