And:
  (gdb) set annotate 1
  (gdb) info line
  ...
  Line ...
     and ends at ...
  /tmp/b/sample.c:...

DDD is reading the output of 'info line' at annotation level 1 and
using sample.c as the filename to set the breakpoint for. As 'link.c'
is loaded instead, 'set breakpoint sample.c:[line #]' this fails.
Oddly enough the HP wdb debugger doesn't read the link.
