Source files as symlinks for 5.2.1

Source files as symlinks for 5.2.1

[Albert Chin]

On Redhat Linux 7.1 with GDB 5.2.1:
  $ mkdir /tmp/a /tmp/b
  $ cd /tmp/a
  $ ln -s ../b/sample.c link.c
  $ ls -ld link.c
  ... link.c -> ../b/sample.c
  $ gcc -g link.c
  $ gdb a.out
  (gdb) list
  (gdb) info source
  Current source file is link.c
  Compilation directory is /tmp/a/
  Located in /tmp/b/sample.c
  Contains 6 lines.
  Source language is c.
  Compiled with stabs debugging format.

Why isn't the source file '/tmp/a/link.c'?

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.
