Hmmm.  The uClibc ttyname() function was considerably reworked
for the 0.9.26 release.  It is possible we missed some sortof
corner case I guess.  The fundamental algorithm we use is the
same as the old one, just a bit more optimized.

What were you getting for ttyname before, with 20031103cvs?
If you revert uClibc/libc/termios/ttyname.c to the old version
does it work for you?  Did you choose the exact same setting
for the UNIX98PTY_ONLY and ASSUME_DEVPTS uClibc config options?
