I'm tidying up a port of gdb 3.5 to the local System V.3 680[23]0
machines.  I have two outstanding problems

(1) If a break point is set in a function which is then executed from a
print or set command to gdb, the breakpoint causes an error ``Cannot
restore previous stack frame''.  This is also seem on a Sun 3/50 running
4.0.

(2) The V.3 machines are compiled entirely with gcc 1.35.  Therefore
small structures are returned in a set of registers.  If a function is
written which returns a structure, executing it from a print or set
(again!) errors as the structure doesn't seem to be where it's expected.
Moreover, I can't see any code to do this right.  Anyone have any ideas?
