| I suspect so. Here is the relevant bit of the trace:
| 1300 MATLAB CALL ioctl(3,_IOW('T',0x30,0x4),0xbfff9c9c)
this is TIOCGPTN... It is going to be tough to do right. If you remove
/dev/ptmx it will work. Another thing to try is to make /emul/linux/dev/ptmx
a symlink that points to nowhere. I am really busy, but I might get some
time to look at it in a week or so.
