(Sorry if you've seen this before but I sent it to bug-gnu-emacs
not realising that bug-gdb existed)
In GDB 2.7 on sibyl (usg-unix-v)
There are 5 parts because outgoing overseas mail from here must be
less than 25k. Part 1 contains a shar archive containing the new
files. Parts 2 to 5 contain shar archives of the patch files to make
the changes to the the existing files. The patch files are context
differences.
Part 5 of 5:
--------------Cut Here-----------------------
# This is a shell archive. Remove anything before this line,
# then unpack it by saving it in a file and typing "sh file".
