Unfortunately the previous posting got lost. 
Hope that doesn't confuse things too much.  I am
including my most recent diffs deal with the problem that a termcap
file name is sometimes sent to init_terminal_io() instead of a 
file name (see <767@accuvax.nwu.edu>) as well as the backspace 
problem.  Here are quotes from the original posting:

I believe that there is a bug in redline.c where the termcap backspace
string is read.  It seems this string "term_backspace"  is never actually
set to the correct value.  

Also I had to add a couple of declartions to get it to compile with the
Sun C compiler (SunOS 4.0) on Sun 3's and 4's.  Here are the diffs.

In builtins.c there are some embedded newlines in strings which the
Sun cc doesn't like:

In shell.c the two functions termination_unwind_protect() and 
throw_to_top_level()  must be declared sighandler for the Sun cc.
