RE: Split ttyname.c to avoid unnecessary dependencies

["Howland Craig D (Craig)" <howland at LGSInnovations dot com>]

Here is a patch that does what Sebastian requested.  I did not include
the regenerated Makefile.in, leaving it to Jeff to do that if it makes
the cut to be put in.  (I did note the regeneration in the ChangeLog.)

OK.  That is pretty far above a minimum configuration
but unused code is unused code.  It should be split.

Can you submit a patch?
