Follow-up Comment #3:

I just had a look under Darwin 11.4.2.  The manual page
TCSETATTR(3) says:


The unsigned integer
     speed_t is typedef'd in the include file <termios.h>.  The value of the
integer corresponds
     directly to the baud rate being represented; however, the following
symbolic values are
     defined:


(The various Bxxx constants then directly map to the value 
xxx, respectively.)

To me, this looks as if the current codebase should work as 
expected.  Is it possible that recent OSX releases changed 
their behaviour here?

The problem with the patch is that it *only* accepts OSX and 
Linux (no *BSD, no Solaris), and that redefining an ioctl 
within application code is basically a no-go.  Nobody would 
guarantee the ioctl is still encoded the same way in the next 
OS release.
