I e-mailed Kris and asked him if he could scan
the ports tree and see what links against ttyname_r(),
since my patch could potentially represent
an ABI change. The old ttyname_r() should never have been exported
from libc, since it was not standards compliant, and did not
have a prototype exported in unistd.h.
I am glad that you took over and do the standard, a better one. Thanks for
