coffread.c is truncated.

It ends on a 4096-byte boundary, which makes me think it got chopped
in a disk operation, so the modification date probably doesn't reflect
the date of the damage.

We checked the backups of Sep 8, 1992 and June 3, 1991, and in both
cases it was truncated.  So we would appear to be out of luck.

Someone found gdb-assorted on a dump of /s3 from cygint on November
19, 1990, but no gdb-2.8.  The guess is that gdb-2.8 moved there after
/s3 moved to /work (which was apparently a new 1gig disk at the time).
